Go client library for interacting with the Anthropic safety-first language model REST APIs. - unfunco/anthropic-sdk-go

github.com/adamchol/go-anthropic-sdk · Open Source Insights · This library provides unofficial Go clients for Anthropic API. It is heavily inspired by the Unofficial Go SDK for OpenAI API by @sashabaranov · go get github.com/adamchol/go-anthropic-sdk ·

package main import ( "fmt" "github.com/modeledge/anthropic-sdk-go/v2" "github.com/modeledge/anthropic-sdk-go/v2/resp" "github.com/modeledge/anthropic-sdk-go/v2/data" ) func main() { c, err := anthropic.New(&anthropic.Config{Key: "your keys", DefaultModel: data.ModelFullInstant}) if err != nil { panic(err) } d, err := c.Send(&anthropic.Sender{ Message: data.MessageModule{ Human: "Do you know Golang, please answer me in the shortest possible way.", }, Sender: &resp.Sender{MaxToken: 1200}, }) if err != nil { panic(err) } fmt.Println(d.Response.String()) ds, err := c.Send(&anthropic.Sender{ Message: data.MessageModule{ Human: "What is its current version number?", }, SessionID: d.ID, Sender: &resp.Sender{MaxToken: 1200}, }) if err != nil { panic(err) } fmt.Println(ds.Response.String()) }

This SDK provides support for tool use, aka function calling. More details can be found in the documentation. This library also provides support for the Anthropic Bedrock API if you install this library with the bedrock extra, e.g.
