Client SDKs - Claude Docs

Konfigurasi tambahan diperlukan untuk menggunakan Client SDKs Anthropic melalui platform mitra. Jika Anda menggunakan Amazon Bedrock, lihat panduan ini; jika Anda menggunakan Google Cloud Vertex AI, lihat panduan ini.

Python

Repositori GitHub perpustakaan Python Contoh:

Python

import anthropic

client = anthropic.Anthropic(
    # defaults to os.environ.get("ANTHROPIC_API_KEY")
    api_key="my_api_key",
)
message = client.messages.create(

TypeScript

Repositori GitHub perpustakaan TypeScript

Meskipun perpustakaan ini dalam TypeScript, perpustakaan ini juga dapat digunakan dalam perpustakaan JavaScript.

Contoh:

TypeScript

import Anthropic from '@anthropic-ai/sdk';

const anthropic = new Anthropic({
  apiKey: 'my_api_key', // defaults to process.env["ANTHROPIC_API_KEY"]
});

const msg = await anthropic.messages.create({
  model: "claude-sonnet-4-5",
  max_tokens: 1024,
  messages: [{ role: "user", content: "Hello, Claude" }],
});
console.log(msg);

String model yang diterima:

Namespace beta dalam client SDKs

Setiap SDK memiliki namespace beta yang tersedia. Ini digunakan untuk fitur baru yang dirilis Anthropic dalam versi beta. Gunakan ini bersama dengan beta headers untuk menggunakan fitur-fitur ini.

import anthropic

client = anthropic.Anthropic(
    # defaults to os.environ.get("ANTHROPIC_API_KEY")
    api_key="my_api_key",
)
message = client.beta.messages.create(
    model="claude-sonnet-4-5",
    max_tokens=1024,
    messages=[
        {"role": "user", "content": "Hello, Claude"}
    ],
    betas=["beta-feature-name"]
)
print(message.content)
