Hanzo AI is OpenAI-compatible, so existing Python code works with zero refactoring. We deeply appreciate the Python Software Foundation team for building and maintaining this open-source project.

## OpenAI SDK (recommended)

python

```
pip install openai from openai import OpenAI client = OpenAI( base_url="https://api.hanzo.ai/v1", api_key="your-hanzo-api-key", ) response = client.chat.completions.create( model="zen4-pro", messages=[{"role": "user", "content": "Hello!"}], ) print(response.choices[0].message.content)
```

## httpx (raw HTTP)

python

```
import httpx, json response = httpx.post( "https://api.hanzo.ai/v1/chat/completions", headers={"Authorization": "Bearer your-hanzo-api-key"}, json={ "model": "zen4-pro", "messages": [{"role": "user", "content": "Hello!"}], }, ) print(response.json()["choices"][0]["message"]["content"])
```

## Async with asyncio

python

```
import asyncio from openai import AsyncOpenAI client = AsyncOpenAI( base_url="https://api.hanzo.ai/v1", api_key="your-hanzo-api-key", ) async def main(): response = await client.chat.completions.create( model="zen4-pro", messages=[{"role": "user", "content": "Hello async!"}], ) print(response.choices[0].message.content) asyncio.run(main())
```

## Environment setup

python

```
# .env HANZO_API_KEY=your-hanzo-api-key # Load in code from dotenv import load_dotenv import os load_dotenv() from openai import OpenAI client = OpenAI( base_url="https://api.hanzo.ai/v1", api_key=os.environ["HANZO_API_KEY"], )
```
