Anthropic Go API Library

Go Reference

The Anthropic Go library provides convenient access to the Anthropic REST API from applications written in Go.

Installation

import (
	"github.com/anthropics/anthropic-sdk-go" // imported as anthropic
)

Or to pin the version:

go get -u 'github.com/anthropics/[email protected]'

Requirements

This library requires Go 1.22+.

Usage

The full API of this library can be found in api.md.

package main

Request fields

The anthropic library uses the omitzero semantics from the Go 1.24+ encoding/json release for request fields.

Required primitive fields (int64, string, etc.) feature the tag `json:"...,required"`. These fields are always serialized, even their zero values.

Optional primitive types are wrapped in a param.Opt[T]. These fields can be set with the provided constructors, anthropic.String(string), anthropic.Int(int64), etc.

Any param.Opt[T], map, slice, struct or string enum uses the tag `json:"...,omitzero"`. Its zero value is considered omitted.

The param.IsOmitted(any) function can confirm the presence of any omitzero field.

p := anthropic.ExampleParams{
	ID:   "id_xxx",                // required property
	Name: anthropic.String("..."), // optional property

	Point: anthropic.Point{
		X: 0,                // required field will serialize as 0
		Y: anthropic.Int(1), // optional field will serialize as 1
		// ... omitted non-required fields will not be serialized
	},

	Origin: anthropic.Origin{}, // the zero value of [Origin] is considered omitted
}

To send null instead of a param.Opt[T], use param.Null[T](). To send null instead of a struct T, use param.NullStruct[T]().

p.Name = param.Null[string]()       // 'null' instead of string
p.Point = param.NullStruct[Point]() // 'null' instead of struct

param.IsNull(p.Name)  // true
param.IsNull(p.Point) // true

Request structs contain a .SetExtraFields(map[string]any) method which can send non-conforming fields in the request body. Extra fields overwrite any struct fields with a matching key.

[!WARNING] For security reasons, only use SetExtraFields with trusted data.

To send a custom value instead of a struct, use param.Override[T](value).

// In cases where the API specifies a given type,
// but you want to send something else, use [SetExtraFields]:
p.SetExtraFields(map[string]any{
	"x": 0.01, // send "x" as a float instead of int
})

// Send a number instead of an object
custom := param.Override[anthropic.FooParams](12)
Request unions

Unions are represented as a struct with fields prefixed by "Of" for each of its variants, only one field can be non-zero. The non-zero field will be serialized.

Sub-properties of the union can be accessed via methods on the union struct. These methods return a mutable pointer to the underlying data, if present.

// Only one field can be non-zero, use param.IsOmitted() to check if a field is set
type AnimalUnionParam struct {
	OfCat *Cat `json:",omitzero,inline`
	OfDog *Dog `json:",omitzero,inline`
}

animal := AnimalUnionParam{
	OfCat: &Cat{
		Name: "Whiskers",
		Owner: PersonParam{
			Address: AddressParam{Street: "3333 Coyote Hill Rd", Zip: 0},
		},
	},
}

// Mutating a field
if address := animal.GetOwner().GetAddress(); address != nil {
	address.ZipCode = 94304
}
Response objects

All fields in response structs are ordinary value types (not pointers or wrappers). Response structs also include a special JSON field containing metadata about each property.

type Animal struct {
	Name   string `json:"name,nullable"`
	Owners int    `json:"owners"`
	Age    int    `json:"age"`
	JSON   struct {
		Name        respjson.Field
		Owner       respjson.Field
		Age         respjson.Field
		ExtraFields map[string]respjson.Field
	} `json:"-"`
}

To handle optional data, use the .Valid() method on the JSON field. .Valid() returns true if a field is not null, not present, or couldn't be marshaled.

If .Valid() is false, the corresponding field will simply be its zero value.

raw := `{"owners": 1, "name": null}`

var res Animal
json.Unmarshal([]byte(raw), &res)

// Accessing regular fields

res.Owners // 1
res.Name   // ""
res.Age    // 0

// Optional field checks

res.JSON.Owners.Valid() // true
res.JSON.Name.Valid()   // false
res.JSON.Age.Valid()    // false

// Raw JSON values

res.JSON.Owners.Raw()                  // "1"
res.JSON.Name.Raw() == "null"          // true
res.JSON.Name.Raw() == respjson.Null   // true
res.JSON.Age.Raw() == ""               // true
res.JSON.Age.Raw() == respjson.Omitted // true

These .JSON structs also include an ExtraFields map containing any properties in the json response that were not specified in the struct. This can be useful for API features not yet present in the SDK.

body := res.JSON.ExtraFields["my_unexpected_field"].Raw()
Response Unions

In responses, unions are represented by a flattened struct containing all possible fields from each of the object variants. To convert it to a variant use the .AsFooVariant() method or the .AsAny() method if present.

If a response value union contains primitive values, primitive fields will be alongside the properties but prefixed with Of and feature the tag json:"...,inline".

type AnimalUnion struct {
	// From variants [Dog], [Cat]
	Owner Person `json:"owner"`
	// From variant [Dog]
	DogBreed string `json:"dog_breed"`
	// From variant [Cat]
	CatBreed string `json:"cat_breed"`
	// ...

	JSON struct {
		Owner respjson.Field
		// ...
	} `json:"-"`
}

// If animal variant
if animal.Owner.Address.ZipCode == "" {
	panic("missing zip code")
}

// Switch on the variant
switch variant := animal.AsAny().(type) {
case Dog:
case Cat:
default:
	panic("unexpected type")
}
RequestOptions

This library uses the functional options pattern. Functions defined in the option package return a RequestOption, which is a closure that mutates a RequestConfig. These options can be supplied to the client or at individual requests. For example:

client := anthropic.NewClient(
	// Adds a header to every request made by the client
	option.WithHeader("X-Some-Header", "custom_header_info"),
)

client.Messages.New(context.TODO(), ...,
	// Override the header
	option.WithHeader("X-Some-Header", "some_other_custom_header_info"),
	// Add an undocumented field to the request body, using sjson syntax
	option.WithJSONSet("some.json.path", map[string]string{"my": "object"}),
)

The request option option.WithDebugLog(nil) may be helpful while debugging.

See the full list of request options.

Pagination

This library provides some conveniences for working with paginated list endpoints.

You can use .ListAutoPaging() methods to iterate through items across all pages:

iter := client.Messages.Batches.ListAutoPaging(context.TODO(), anthropic.MessageBatchListParams{
	Limit: anthropic.Int(20),
})
// Automatically fetches more pages as needed.
for iter.Next() {
	messageBatch := iter.Current()
	fmt.Printf("%+v\n", messageBatch)
}
if err := iter.Err(); err != nil {
	panic(err.Error())
}

Or you can use simple .List() methods to fetch a single page and receive a standard response object with additional helper methods like .GetNextPage(), e.g.:

page, err := client.Messages.Batches.List(context.TODO(), anthropic.MessageBatchListParams{
	Limit: anthropic.Int(20),
})
for page != nil {
	for _, batch := range page.Data {
		fmt.Printf("%+v\n", batch)
	}
	page, err = page.GetNextPage()
}
if err != nil {
	panic(err.Error())
}
Errors

When the API returns a non-success status code, we return an error with type *anthropic.Error. This contains the StatusCode, *http.Request, and *http.Response values of the request, as well as the JSON of the error body (much like other response objects in the SDK). The error also includes the RequestID from the response headers, which is useful for troubleshooting with Anthropic support.

To handle errors, we recommend that you use the errors.As pattern:

_, err := client.Messages.New(context.TODO(), anthropic.MessageNewParams{
	MaxTokens: 1024,
	Messages: []anthropic.MessageParam{{
		Content: []anthropic.ContentBlockParamUnion{{
			OfText: &anthropic.TextBlockParam{Text: "What is a quaternion?", CacheControl: anthropic.CacheControlEphemeralParam{TTL: anthropic.CacheControlEphemeralTTLTTL5m}, Citations: []anthropic.TextCitationParamUnion{{
				OfCharLocation: &anthropic.CitationCharLocationParam{CitedText: "cited_text", DocumentIndex: 0, DocumentTitle: anthropic.String("x"), EndCharIndex: 0, StartCharIndex: 0},
			}}},
		}},
		Role: anthropic.MessageParamRoleUser,
	}},
	Model: anthropic.ModelClaudeSonnet4_5_20250929,
})
if err != nil {
	var apierr *anthropic.Error
	if errors.As(err, &apierr) {
		println("Request ID:", apierr.RequestID)
		println(string(apierr.DumpRequest(true)))  // Prints the serialized HTTP request
		println(string(apierr.DumpResponse(true))) // Prints the serialized HTTP response
	}
	panic(err.Error()) // GET "/v1/messages": 400 Bad Request (Request-ID: req_xxx) { ... }
}

When other errors occur, they are returned unwrapped; for example, if HTTP transport fails, you might receive *url.Error wrapping *net.OpError.

Timeouts

Requests do not time out by default; use context to configure a timeout for a request lifecycle.

Note that if a request is retried, the context timeout does not start over. To set a per-retry timeout, use option.WithRequestTimeout().

// This sets the timeout for the request, including all the retries.
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Minute)
defer cancel()
client.Messages.New(
	ctx,
	anthropic.MessageNewParams{
		MaxTokens: 1024,
		Messages: []anthropic.MessageParam{{
			Content: []anthropic.ContentBlockParamUnion{{
				OfRequestTextBlock: &anthropic.TextBlockParam{Text: "What is a quaternion?"},
			}},
			Role: anthropic.MessageParamRoleUser,
		}},
		Model: anthropic.ModelClaudeOpus4_5_20251101,
	},
	// This sets the per-retry timeout
	option.WithRequestTimeout(20*time.Second),
)
Long Requests

[!IMPORTANT] We highly encourage you use the streaming Messages API for longer running requests.

We do not recommend setting a large MaxTokens value without using streaming as some networks may drop idle connections after a certain period of time, which can cause the request to fail or timeout without receiving a response from Anthropic.

This SDK will also return an error if a non-streaming request is expected to be above roughly 10 minutes long. Calling .Messages.NewStreaming() or setting a custom timeout disables this error.

File uploads

Request parameters that correspond to file uploads in multipart requests are typed as io.Reader. The contents of the io.Reader will by default be sent as a multipart form part with the file name of "anonymous_file" and content-type of "application/octet-stream", so we recommend always specifyig a custom content-type with the anthropic.File(reader io.Reader, filename string, contentType string) helper we provide to easily wrap any io.Reader with the appropriate file name and content type.

// A file from the file system
file, err := os.Open("/path/to/file.json")
anthropic.BetaFileUploadParams{
	File: anthropic.File(file, "custom-name.json", "application/json"),
	Betas: []anthropic.AnthropicBeta{anthropic.AnthropicBetaFilesAPI2025_04_14},
}

// A file from a string
anthropic.BetaFileUploadParams{
	File: anthropic.File(strings.NewReader("my file contents"), "custom-name.json", "application/json"),
	Betas: []anthropic.AnthropicBeta{anthropic.AnthropicBetaFilesAPI2025_04_14},
}

The file name and content-type can also be customized by implementing Name() string or ContentType() string on the run-time type of io.Reader. Note that os.File implements Name() string, so a file returned by os.Open will be sent with the file name on disk.

Retries

Certain errors will be automatically retried 2 times by default, with a short exponential backoff. We retry by default all connection errors, 408 Request Timeout, 409 Conflict, 429 Rate Limit, and >=500 Internal errors.

You can use the WithMaxRetries option to configure or disable this:

// Configure the default for all requests:
client := anthropic.NewClient(
	option.WithMaxRetries(0), // default is 2
)

// Override per-request:
client.Messages.New(
	context.TODO(),
	anthropic.MessageNewParams{
		MaxTokens: 1024,
		Messages: []anthropic.MessageParam{{
			Content: []anthropic.ContentBlockParamUnion{{
				OfRequestTextBlock: &anthropic.TextBlockParam{Text: "What is a quaternion?"},
			}},
			Role: anthropic.MessageParamRoleUser,
		}},
		Model: anthropic.ModelClaudeOpus4_5_20251101,
	},
	option.WithMaxRetries(5),
)
Accessing raw response data (e.g. response headers)

You can access the raw HTTP response data by using the option.WithResponseInto() request option. This is useful when you need to examine response headers, status codes, or other details.

// Create a variable to store the HTTP response
var response *http.Response
message, err := client.Messages.New(
	context.TODO(),
	anthropic.MessageNewParams{
		MaxTokens: 1024,
		Messages: []anthropic.MessageParam{{
			Content: []anthropic.ContentBlockParamUnion{{
				OfText: &anthropic.TextBlockParam{Text: "What is a quaternion?", CacheControl: anthropic.CacheControlEphemeralParam{TTL: anthropic.CacheControlEphemeralTTLTTL5m}, Citations: []anthropic.TextCitationParamUnion{{
					OfCharLocation: &anthropic.CitationCharLocationParam{CitedText: "cited_text", DocumentIndex: 0, DocumentTitle: anthropic.String("x"), EndCharIndex: 0, StartCharIndex: 0},
				}}},
			}},
			Role: anthropic.MessageParamRoleUser,
		}},
		Model: anthropic.ModelClaudeOpus4_5_20251101,
	},
	option.WithResponseInto(&response),
)
if err != nil {
	// handle error
}
fmt.Printf("%+v\n", message)

fmt.Printf("Status Code: %d\n", response.StatusCode)
fmt.Printf("Headers: %+#v\n", response.Header)
Making custom/undocumented requests

This library is typed for convenient access to the documented API. If you need to access undocumented endpoints, params, or response properties, the library can still be used.

Undocumented endpoints

To make requests to undocumented endpoints, you can use client.Get, client.Post, and other HTTP verbs. RequestOptions on the client, such as retries, will be respected when making these requests.

var (
    // params can be an io.Reader, a []byte, an encoding/json serializable object,
    // or a "…Params" struct defined in this library.
    params map[string]any

    // result can be an []byte, *http.Response, a encoding/json deserializable object,
    // or a model defined in this library.
    result *http.Response
)
err := client.Post(context.Background(), "/unspecified", params, &result)
if err != nil {
    …
}
Undocumented request params

To make requests using undocumented parameters, you may use either the option.WithQuerySet() or the option.WithJSONSet() methods.

params := FooNewParams{
    ID:   "id_xxxx",
    Data: FooNewParamsData{
        FirstName: anthropic.String("John"),
    },
}
client.Foo.New(context.Background(), params, option.WithJSONSet("data.last_name", "Doe"))
Undocumented response properties

To access undocumented response properties, you may either access the raw JSON of the response as a string with result.JSON.RawJSON(), or get the raw JSON of a particular field on the result with result.JSON.Foo.Raw().

Any fields that are not present on the response struct will be saved and can be accessed by result.JSON.ExtraFields() which returns the extra fields as a map[string]Field.

Middleware

We provide option.WithMiddleware which applies the given middleware to requests.

func Logger(req *http.Request, next option.MiddlewareNext) (res *http.Response, err error) {
	// Before the request
	start := time.Now()
	LogReq(req)

	// Forward the request to the next handler
	res, err = next(req)

	// Handle stuff after the request
	end := time.Now()
	LogRes(res, err, start - end)

    return res, err
}

client := anthropic.NewClient(
	option.WithMiddleware(Logger),
)

When multiple middlewares are provided as variadic arguments, the middlewares are applied left to right. If option.WithMiddleware is given multiple times, for example first in the client then the method, the middleware in the client will run first and the middleware given in the method will run next.

You may also replace the default http.Client with option.WithHTTPClient(client). Only one http client is accepted (this overwrites any previous client) and receives requests after any middleware has been applied.

Amazon Bedrock

To use this library with Amazon Bedrock, use the bedrock request option bedrock.WithLoadDefaultConfig(…) which reads the default config.

Importing the bedrock library also globally registers a decoder for application/vnd.amazon.eventstream for streaming.

package main

import (
	"github.com/anthropics/anthropic-sdk-go"
	"github.com/anthropics/anthropic-sdk-go/bedrock"
)

func main() {
	client := anthropic.NewClient(
		bedrock.WithLoadDefaultConfig(context.Background()),
	)
}

If you already have an aws.Config, you can also use it directly with bedrock.WithConfig(cfg).

Read more about Anthropic and Amazon Bedrock here.

Google Vertex AI

To use this library with Google Vertex AI, use the request option vertex.WithGoogleAuth(…) which reads the Application Default Credentials.

package main

import (
	"context"

	"github.com/anthropics/anthropic-sdk-go"
	"github.com/anthropics/anthropic-sdk-go/vertex"
)

func main() {
	client := anthropic.NewClient(
		vertex.WithGoogleAuth(context.Background(), "us-central1", "id-xxx"),
	)
}

If you already have *google.Credentials, you can also use it directly with vertex.WithCredentials(ctx, region, projectId, creds).

Read more about Anthropic and Google Vertex here.

Semantic versioning

This package generally follows SemVer conventions, though certain backwards-incompatible changes may be released as minor versions:

  1. Changes to library internals which are technically public but not intended or documented for external use. (Please open a GitHub issue to let us know if you are relying on such internals.)
  2. Changes that we do not expect to impact the vast majority of users in practice.

We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.

We are keen for your feedback; please open an issue with questions, bugs, or suggestions.

type BetaMessageBatchNewParamsRequestParams 

type BetaMessageBatchNewParamsRequestParams struct {
	// The maximum number of tokens to generate before stopping.
	//
	// Note that our models may stop _before_ reaching this maximum. This parameter
	// only specifies the absolute maximum number of tokens to generate.
	//
	// Different models have different maximum values for this parameter. See
	// [models](https://docs.claude.com/en/docs/models-overview) for details.
	MaxTokens int64 `json:"max_tokens,required"`
	// Input messages.
	//
	// Our models are trained to operate on alternating `user` and `assistant`
	// conversational turns. When creating a new `Message`, you specify the prior
	// conversational turns with the `messages` parameter, and the model then generates
	// the next `Message` in the conversation. Consecutive `user` or `assistant` turns
	// in your request will be combined into a single turn.
	//
	// Each input message must be an object with a `role` and `content`. You can
	// specify a single `user`-role message, or you can include multiple `user` and
	// `assistant` messages.
	//
	// If the final message uses the `assistant` role, the response content will
	// continue immediately from the content in that message. This can be used to
	// constrain part of the model's response.
	//
	// Example with a single `user` message:
	//
	// “`json
	// [{ "role": "user", "content": "Hello, Claude" }]
	// “`
	//
	// Example with multiple conversational turns:
	//
	// “`json
	// [
	//
	//	{ "role": "user", "content": "Hello there." },
	//	{ "role": "assistant", "content": "Hi, I'm Claude. How can I help you?" },
	//	{ "role": "user", "content": "Can you explain LLMs in plain English?" }
	//
	// ]

	//
	// Example with a partially-filled response from Claude:
	//

	//	  "content": "What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun"
	//	},
	//	{ "role": "assistant", "content": "The best answer is (" }
	//
	// ]
	// “`
	//
	// Each input message `content` may be either a single `string` or an array of
	// content blocks, where each block has a specific `type`. Using a `string` for
	// `content` is shorthand for an array of one content block of type `"text"`. The
	// following input messages are equivalent:
	//
	// “`json
	// { "role": "user", "content": "Hello, Claude" }

	ToolChoice BetaToolChoiceUnionParam `json:"tool_choice,omitzero"`
	// Definitions of tools that the model may use.
	//
	// If you include `tools` in your API request, the model may return `tool_use`
	// content blocks that represent the model's use of those tools. You can then run
	// those tools using the tool input generated by the model and then optionally
	// return results back to the model using `tool_result` content blocks.
	//
	// There are two types of tools: **client tools** and **server tools**. The
	// behavior described below applies to client tools. For
	// [server tools](https://docs.claude.com/en/docs/agents-and-tools/tool-use/overview#server-tools),
	// see their individual documentation as each has its own behavior (e.g., the
	// [web search tool](https://docs.claude.com/en/docs/agents-and-tools/tool-use/web-search-tool)).
	//
	// Each tool definition includes:
	//
	//   - `name`: Name of the tool.
	//   - `description`: Optional, but strongly-recommended description of the tool.
	//   - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
	//     tool `input` shape that the model will produce in `tool_use` output content
	//     blocks.
	//
	// For example, if you defined `tools` as:
	//
	// “`json
	// [
	//
	//	{
	//	  "name": "get_stock_price",
	//	  "description": "Get the current stock price for a given ticker symbol.",

	//	    "required": ["ticker"]
	//	  }
	//	}
	//
	// ]
	// “`
	//
	// And then asked the model "What's the S&P 500 at today?", the model might produce
	// `tool_use` content blocks in the response like this:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_use",

	//	  "input": { "ticker": "^GSPC" }
	//	}
	//
	// ]
	// “`
	//
	// You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
	// input, and return the following back to the model in a subsequent `user`
	// message:
	//
	// “`json
	// [

	//	  "content": "259.75 USD"
	//	}
	//
	// ]
	// “`
	//
	// Tools can be used for workflows that include running client-side tools and
	// functions, or more generally whenever you want the model to produce a particular
	// JSON structure of output.

type BetaMessageBatchService 

type BetaMessageBatchService struct {
	Options []option.RequestOption
}

BetaMessageBatchService contains methods and other services that help with interacting with the anthropic API.

Note, unlike clients, this service does not read variables from the environment automatically. You should not instantiate this service directly, and instead use the NewBetaMessageBatchService method instead.

func NewBetaMessageBatchService 

func NewBetaMessageBatchService(opts ...option.RequestOption) (r BetaMessageBatchService)

NewBetaMessageBatchService generates a new service that applies the given options to each request. These options are applied after the parent client's options (if there is one), and before any request-specific options.

func (*BetaMessageBatchService) Cancel 

func (r *BetaMessageBatchService) Cancel(ctx context.Context, messageBatchID string, body BetaMessageBatchCancelParams, opts ...option.RequestOption) (res *BetaMessageBatch, err error)

Batches may be canceled any time before processing ends. Once cancellation is initiated, the batch enters a `canceling` state, at which time the system may complete any in-progress, non-interruptible requests before finalizing cancellation.

The number of canceled requests is specified in `request_counts`. To determine which requests were canceled, check the individual results within the batch. Note that cancellation may not result in any canceled requests if they were non-interruptible.

func (*BetaMessageBatchService) Delete 

func (r *BetaMessageBatchService) Delete(ctx context.Context, messageBatchID string, body BetaMessageBatchDeleteParams, opts ...option.RequestOption) (res *BetaDeletedMessageBatch, err error)

Delete a Message Batch.

Message Batches can only be deleted once they've finished processing. If you'd like to delete an in-progress batch, you must first cancel it.

func (*BetaMessageBatchService) Get 

func (r *BetaMessageBatchService) Get(ctx context.Context, messageBatchID string, query BetaMessageBatchGetParams, opts ...option.RequestOption) (res *BetaMessageBatch, err error)

This endpoint is idempotent and can be used to poll for Message Batch completion. To access the results of a Message Batch, make a request to the `results_url` field in the response.

func (*BetaMessageBatchService) List 

func (r *BetaMessageBatchService) List(ctx context.Context, params BetaMessageBatchListParams, opts ...option.RequestOption) (res *pagination.Page[BetaMessageBatch], err error)

List all Message Batches within a Workspace. Most recently created batches are returned first.

func (*BetaMessageBatchService) New 

func (r *BetaMessageBatchService) New(ctx context.Context, params BetaMessageBatchNewParams, opts ...option.RequestOption) (res *BetaMessageBatch, err error)

Send a batch of Message creation requests.

The Message Batches API can be used to process multiple Messages API requests at once. Once a Message Batch is created, it begins processing immediately. Batches can take up to 24 hours to complete.

Learn more about the Message Batches API in our [user guide](https://docs.claude.com/en/docs/build-with-claude/batch-processing)

func (*BetaMessageBatchService) ResultsStreaming 

func (r *BetaMessageBatchService) ResultsStreaming(ctx context.Context, messageBatchID string, query BetaMessageBatchResultsParams, opts ...option.RequestOption) (stream *jsonl.Stream[BetaMessageBatchIndividualResponse])

Streams the results of a Message Batch as a `.jsonl` file.

Each line in the file is a JSON object containing the result of a single request in the Message Batch. Results are not guaranteed to be in the same order as requests. Use the `custom_id` field to match results to requests.

type BetaMessageCountTokensParams struct {
	// Input messages.
	//
	// Our models are trained to operate on alternating `user` and `assistant`

	//
	// Each input message must be an object with a `role` and `content`. You can

	//
	// If the final message uses the `assistant` role, the response content will

	//
	// Each input message `content` may be either a single `string` or an array of

	Thinking BetaThinkingConfigParamUnion `json:"thinking,omitzero"`
	// How the model should use the provided tools. The model can use a specific tool,

	ToolChoice BetaToolChoiceUnionParam `json:"tool_choice,omitzero"`
	// Definitions of tools that the model may use.
	//
	// If you include `tools` in your API request, the model may return `tool_use`
	// content blocks that represent the model's use of those tools. You can then run
	// those tools using the tool input generated by the model and then optionally
	// return results back to the model using `tool_result` content blocks.
	//
	// There are two types of tools: **client tools** and **server tools**. The
	// behavior described below applies to client tools. For
	// [server tools](https://docs.claude.com/en/docs/agents-and-tools/tool-use/overview#server-tools),
	// see their individual documentation as each has its own behavior (e.g., the
	// [web search tool](https://docs.claude.com/en/docs/agents-and-tools/tool-use/web-search-tool)).
	//
	// Each tool definition includes:
	//
	//   - `name`: Name of the tool.
	//   - `description`: Optional, but strongly-recommended description of the tool.
	//   - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
	//     tool `input` shape that the model will produce in `tool_use` output content
	//     blocks.
	//
	// For example, if you defined `tools` as:
	//
	// “`json
	// [
	//
	//	{
	//	  "name": "get_stock_price",
	//	  "description": "Get the current stock price for a given ticker symbol.",

	//	      "ticker": {
	//	        "type": "string",
	//	        "description": "The stock ticker symbol, e.g. AAPL for Apple Inc."
	//	      }
	//	    },
	//	    "required": ["ticker"]
	//	  }
	//	}
	//
	// ]
	// “`
	//
	// And then asked the model "What's the S&P 500 at today?", the model might produce
	// `tool_use` content blocks in the response like this:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_use",
	//	  "id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
	//	  "name": "get_stock_price",
	//	  "input": { "ticker": "^GSPC" }
	//	}
	//
	// ]
	// “`
	//
	// You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
	// input, and return the following back to the model in a subsequent `user`
	// message:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_result",

	//	  "content": "259.75 USD"
	//	}
	//
	// ]
	// “`
	//
	// Tools can be used for workflows that include running client-side tools and
	// functions, or more generally whenever you want the model to produce a particular
	// JSON structure of output.

	// those tools using the tool input generated by the model and then optionally
	// return results back to the model using `tool_result` content blocks.
	//
	// There are two types of tools: **client tools** and **server tools**. The
	// behavior described below applies to client tools. For
	// [server tools](https://docs.claude.com/en/docs/agents-and-tools/tool-use/overview#server-tools),
	// see their individual documentation as each has its own behavior (e.g., the
	// [web search tool](https://docs.claude.com/en/docs/agents-and-tools/tool-use/web-search-tool)).
	//
	// Each tool definition includes:
	//
	//   - `name`: Name of the tool.
	//   - `description`: Optional, but strongly-recommended description of the tool.
	//   - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
	//     tool `input` shape that the model will produce in `tool_use` output content
	//     blocks.
	//
	// For example, if you defined `tools` as:
	//
	// “`json
	// [
	//
	//	{
	//	  "name": "get_stock_price",
	//	  "description": "Get the current stock price for a given ticker symbol.",

	//	    "required": ["ticker"]
	//	  }
	//	}
	//
	// ]
	// “`
	//
	// And then asked the model "What's the S&P 500 at today?", the model might produce
	// `tool_use` content blocks in the response like this:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_use",
	//	  "id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
	//	  "name": "get_stock_price",
	//	  "input": { "ticker": "^GSPC" }
	//	}
	//
	// ]
	// “`
	//
	// You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
	// input, and return the following back to the model in a subsequent `user`
	// message:
	//
	// “`json

type Client

	Options     []option.RequestOption
	Completions CompletionService
	Messages    MessageService
	Models      ModelService
	Beta        BetaService
}

Client creates a struct with services and top level methods that help with interacting with the anthropic API. You should not instantiate this client directly, and instead use the NewClient method instead.

func NewClient 

func NewClient(opts ...option.RequestOption) (r Client)

NewClient generates a new client with the default option read from the environment (ANTHROPIC_API_KEY, ANTHROPIC_AUTH_TOKEN, ANTHROPIC_BASE_URL). The option passed in as arguments are applied after these default arguments, and all option will be passed down to the services and requests that this client makes.

func (*Client) Delete 

func (r *Client) Delete(ctx context.Context, path string, params any, res any, opts ...option.RequestOption) error

Delete makes a DELETE request with the given URL, params, and optionally deserializes to a response. See [Execute] documentation on the params and response.

func (*Client) Execute 

func (r *Client) Execute(ctx context.Context, method string, path string, params any, res any, opts ...option.RequestOption) error

Execute makes a request with the given context, method, URL, request params, response, and request options. This is useful for hitting undocumented endpoints while retaining the base URL, auth, retries, and other options from the client.

If a byte slice or an io.Reader is supplied to params, it will be used as-is for the request body.

The params is by default serialized into the body using encoding/json. If your type implements a MarshalJSON function, it will be used instead to serialize the request. If a URLQuery method is implemented, the returned url.Values will be used as query strings to the url.

If your params struct uses param.Field, you must provide either [MarshalJSON], [URLQuery], and/or [MarshalForm] functions. It is undefined behavior to use a struct uses param.Field without specifying how it is serialized.

Any "…Params" object defined in this library can be used as the request argument. Note that 'path' arguments will not be forwarded into the url.

The response body will be deserialized into the res variable, depending on its type:

  • A pointer to a *http.Response is populated by the raw response.
  • A pointer to a byte array will be populated with the contents of the request body.
  • A pointer to any other type uses this library's default JSON decoding, which respects UnmarshalJSON if it is defined on the type.
  • A nil value will not read the response body.

For even greater flexibility, see option.WithResponseInto and option.WithResponseBodyInto.

func (*Client) Get 

func (r *Client) Get(ctx context.Context, path string, params any, res any, opts ...option.RequestOption) error

Get makes a GET request with the given URL, params, and optionally deserializes to a response. See [Execute] documentation on the params and response.

func (*Client) Patch 

func (r *Client) Patch(ctx context.Context, path string, params any, res any, opts ...option.RequestOption) error

Patch makes a PATCH request with the given URL, params, and optionally deserializes to a response. See [Execute] documentation on the params and response.

func (*Client) Post 

func (r *Client) Post(ctx context.Context, path string, params any, res any, opts ...option.RequestOption) error

Post makes a POST request with the given URL, params, and optionally deserializes to a response. See [Execute] documentation on the params and response.

func (*Client) Put 

func (r *Client) Put(ctx context.Context, path string, params any, res any, opts ...option.RequestOption) error

Put makes a PUT request with the given URL, params, and optionally deserializes to a response. See [Execute] documentation on the params and response.

type MessageBatchNewParamsRequestParams 

type MessageBatchNewParamsRequestParams struct {
	// The maximum number of tokens to generate before stopping.
	//
	// Note that our models may stop _before_ reaching this maximum. This parameter
	// only specifies the absolute maximum number of tokens to generate.
	//
	// Different models have different maximum values for this parameter. See
	// [models](https://docs.claude.com/en/docs/models-overview) for details.
	MaxTokens int64 `json:"max_tokens,required"`
	// Input messages.
	//
	// Our models are trained to operate on alternating `user` and `assistant`
	// conversational turns. When creating a new `Message`, you specify the prior
	// conversational turns with the `messages` parameter, and the model then generates
	// the next `Message` in the conversation. Consecutive `user` or `assistant` turns
	// in your request will be combined into a single turn.
	//
	// Each input message must be an object with a `role` and `content`. You can
	// specify a single `user`-role message, or you can include multiple `user` and
	// `assistant` messages.
	//
	// If the final message uses the `assistant` role, the response content will
	// continue immediately from the content in that message. This can be used to
	// constrain part of the model's response.
	//
	// Example with a single `user` message:
	//
	// “`json
	// [{ "role": "user", "content": "Hello, Claude" }]
	// “`
	//
	// Example with multiple conversational turns:
	//
	// “`json
	// [
	//
	//	{ "role": "user", "content": "Hello there." },
	//	{ "role": "assistant", "content": "Hi, I'm Claude. How can I help you?" },
	//	{ "role": "user", "content": "Can you explain LLMs in plain English?" }
	//
	// ]
	// “`
	//
	// Example with a partially-filled response from Claude:
	//
	// “`json

	//
	//	{
	//	  "role": "user",
	//	  "content": "What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun"
	//	},
	//	{ "role": "assistant", "content": "The best answer is (" }
	//
	// ]
	// “`
	//
	// Each input message `content` may be either a single `string` or an array of
	// content blocks, where each block has a specific `type`. Using a `string` for
	// `content` is shorthand for an array of one content block of type `"text"`. The
	// following input messages are equivalent:
	//
	// “`json
	// { "role": "user", "content": "Hello, Claude" }

	Thinking ThinkingConfigParamUnion `json:"thinking,omitzero"`
	// How the model should use the provided tools. The model can use a specific tool,
	// any available tool, decide by itself, or not use tools at all.
	ToolChoice ToolChoiceUnionParam `json:"tool_choice,omitzero"`
	// Definitions of tools that the model may use.
	//
	// If you include `tools` in your API request, the model may return `tool_use`
	// content blocks that represent the model's use of those tools. You can then run
	// those tools using the tool input generated by the model and then optionally
	// return results back to the model using `tool_result` content blocks.
	//
	// There are two types of tools: **client tools** and **server tools**. The
	// behavior described below applies to client tools. For
	// [server tools](https://docs.claude.com/en/docs/agents-and-tools/tool-use/overview#server-tools),
	// see their individual documentation as each has its own behavior (e.g., the
	// [web search tool](https://docs.claude.com/en/docs/agents-and-tools/tool-use/web-search-tool)).
	//
	// Each tool definition includes:
	//
	//   - `name`: Name of the tool.
	//   - `description`: Optional, but strongly-recommended description of the tool.
	//   - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
	//     tool `input` shape that the model will produce in `tool_use` output content
	//     blocks.
	//
	// For example, if you defined `tools` as:
	//
	// “`json
	// [
	//
	//	{
	//	  "name": "get_stock_price",
	//	  "description": "Get the current stock price for a given ticker symbol.",

	//	    },
	//	    "required": ["ticker"]
	//	  }
	//	}
	//
	// ]
	// “`
	//
	// And then asked the model "What's the S&P 500 at today?", the model might produce
	// `tool_use` content blocks in the response like this:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_use",
	//	  "id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
	//	  "name": "get_stock_price",
	//	  "input": { "ticker": "^GSPC" }
	//	}
	//
	// ]
	// “`
	//
	// You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
	// input, and return the following back to the model in a subsequent `user`
	// message:
	//
	// “`json
	// [
	//
	//	{
	//	  "type": "tool_result",

	//	  "content": "259.75 USD"
	//	}
	//
	// ]
	// “`
	//
	// Tools can be used for workflows that include running client-side tools and
	// functions, or more generally whenever you want the model to produce a particular
	// JSON structure of output.
	//
	// See our [guide](https://docs.claude.com/en/docs/tool-use) for more details.

type MessageBatchService 

type MessageBatchService struct {
	Options []option.RequestOption
}

MessageBatchService contains methods and other services that help with interacting with the anthropic API.

Note, unlike clients, this service does not read variables from the environment automatically. You should not instantiate this service directly, and instead use the NewMessageBatchService method instead.

func NewMessageBatchService 

func NewMessageBatchService(opts ...option.RequestOption) (r MessageBatchService)

NewMessageBatchService generates a new service that applies the given options to each request. These options are applied after the parent client's options (if there is one), and before any request-specific options.

func (*MessageBatchService) Cancel 

func (r *MessageBatchService) Cancel(ctx context.Context, messageBatchID string, opts ...option.RequestOption) (res *MessageBatch, err error)

Batches may be canceled any time before processing ends. Once cancellation is initiated, the batch enters a `canceling` state, at which time the system may complete any in-progress, non-interruptible requests before finalizing cancellation.

The number of canceled requests is specified in `request_counts`. To determine which requests were canceled, check the individual results within the batch. Note that cancellation may not result in any canceled requests if they were non-interruptible.

Learn more about the Message Batches API in our [user guide](https://docs.claude.com/en/docs/build-with-claude/batch-processing)

func (*MessageBatchService) Delete 

func (r *MessageBatchService) Delete(ctx context.Context, messageBatchID string, opts ...option.RequestOption) (res *DeletedMessageBatch, err error)

Delete a Message Batch.

Message Batches can only be deleted once they've finished processing. If you'd like to delete an in-progress batch, you must first cancel it.

Learn more about the Message Batches API in our [user guide](https://docs.claude.com/en/docs/build-with-claude/batch-processing)

func (*MessageBatchService) Get 

func (r *MessageBatchService) Get(ctx context.Context, messageBatchID string, opts ...option.RequestOption) (res *MessageBatch, err error)

This endpoint is idempotent and can be used to poll for Message Batch completion. To access the results of a Message Batch, make a request to the `results_url` field in the response.

func (*MessageBatchService) New 

func (r *MessageBatchService) New(ctx context.Context, body MessageBatchNewParams, opts ...option.RequestOption) (res *MessageBatch, err error)

Send a batch of Message creation requests.

The Message Batches API can be used to process multiple Messages API requests at once. Once a Message Batch is created, it begins processing immediately. Batches can take up to 24 hours to complete.

func (*MessageBatchService) ResultsStreaming 

func (r *MessageBatchService) ResultsStreaming(ctx context.Context, messageBatchID string, opts ...option.RequestOption) (stream *jsonl.Stream[MessageBatchIndividualResponse])

Streams the results of a Message Batch as a `.jsonl` file.

Each line in the file is a JSON object containing the result of a single request in the Message Batch. Results are not guaranteed to be in the same order as requests. Use the `custom_id` field to match results to requests.

type MessageCountTokensParams struct {
	// Input messages.
	//
	// Our models are trained to operate on alternating `user` and `assistant`
	// conversational turns. When creating a new `Message`, you specify the prior
	// conversational turns with the `messages` parameter, and the model then generates
	// the next `Message` in the conversation. Consecutive `user` or `assistant` turns
	// in your request will be combined into a single turn.
	//
	// Each input message must be an object with a `role` and `content`. You can
	// specify a single `user`-role message, or you can include multiple `user` and
	// `assistant` messages.
	//
	// If the final message uses the `assistant` role, the response content will
	// continue immediately from the content in that message. This can be used to
	// constrain part of the model's response.
	//
	// Example with a single `user` message:
	//
	// “`json

	//
	// Each input message `content` may be either a single `string` or an array of

MessageService contains methods and other services that help with interacting with the anthropic API.

Note, unlike clients, this service does not read variables from the environment automatically. You should not instantiate this service directly, and instead use the NewMessageService method instead.

func NewMessageService 

func NewMessageService(opts ...option.RequestOption) (r MessageService)

NewMessageService generates a new service that applies the given options to each request. These options are applied after the parent client's options (if there is one), and before any request-specific options.

func (*MessageService) CountTokens 

func (r *MessageService) CountTokens(ctx context.Context, body MessageCountTokensParams, opts ...option.RequestOption) (res *MessageTokensCount, err error)

Count the number of tokens in a Message.

The Token Count API can be used to count the number of tokens in a Message, including tools, images, and documents, without creating it.

Learn more about token counting in our [user guide](https://docs.claude.com/en/docs/build-with-claude/token-counting)

func (*MessageService) New 

func (r *MessageService) New(ctx context.Context, body MessageNewParams, opts ...option.RequestOption) (res *Message, err error)

Send a structured list of input messages with text and/or image content, and the model will generate the next message in the conversation.

The Messages API can be used for either single queries or stateless multi-turn conversations.

Learn more about the Messages API in our [user guide](https://docs.claude.com/en/docs/initial-setup)

Note: If you choose to set a timeout for this request, we recommend 10 minutes.

func (*MessageService) NewStreaming 

func (r *MessageService) NewStreaming(ctx context.Context, body MessageNewParams, opts ...option.RequestOption) (stream *ssestream.Stream[MessageStreamEventUnion])

Send a structured list of input messages with text and/or image content, and the model will generate the next message in the conversation.
