Anthropic SDK for Go

Note

This is not an official SDK, and I am not affiliated with Anthropic.
Official SDKs from Anthropic are available for Python, and TypeScript/JavaScript.

Client library for interacting with the Anthropic safety-first language model REST APIs.
Documentation for the REST API can be found at docs.anthropic.com.

Getting started

Requirements

• Claude API key
• Go 1.22+

Installation and usage

Import the module and run the go get command without any arguments to resolve and add the SDK to your dependencies.

import "github.com/unfunco/anthropic-sdk-go"

Construct a new REST API client with a http.Client derived from a Transport containing your Claude API key. The derived HTTP client will automatically add the API key as a header to each request sent to the API.

transport := anthropic.NewTransport(os.Getenv("ANTHROPIC_API_KEY"))
claude := anthropic.NewClient(transport.Client())

Once constructed, you can use the client to interact with the REST API.

data, _, err := claude.Messages.Create(
    context.Background(),
    &anthropic.CreateMessageInput{
        MaxTokens: 1024,
        Messages: []anthropic.Message{
            {
                Content: "Hello, Claude!",
                Role:    "user",
            },
        },
        Model: anthropic.Claude3Opus20240229,
    },
)

Development and testing

Clone the repository and change into the anthropic-sdk-go directory.

git clone git@github.com:unfunco/anthropic-sdk-go.git
cd anthropic-sdk-go

Run the unit tests with coverage to ensure everything is working as expected.
