Anthropic SDK

ai& exposes Anthropic-compatible endpoints alongside its OpenAI surface. Use the official anthropic SDKs by overriding the base URL.

Setup

Python
Node.js

pip install anthropic

from anthropic import Anthropic

client = Anthropic(
    base_url="https://api.aiand.com",
    api_key="sk-your-aiand-api-key",
)

npm install @anthropic-ai/sdk

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

const client = new Anthropic({
  baseURL: "https://api.aiand.com",
  apiKey: "sk-your-aiand-api-key",
});

Messages

response = client.messages.create(
    model="...",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.content[0].text)

Streaming

with client.messages.stream(
    model="...",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello"}],
) as stream:
    for text in stream.text_stream:
        print(text, end="")

Files

The Anthropic Files API works too — selected by the SDK’s anthropic-version header:

file = client.beta.files.upload(file=open("cat.png", "rb"))

See OpenAI vs Anthropic shape for how the dual-emit works.
