# OpenAI Python SDK with zurelay

> Official OpenAI library for Python. Made by OpenAI.

Source: https://zurelay.com/docs/integrations/openai-python

The examples use `claude-opus-5-5`. Any model ID from [the models page](https://zurelay.com/docs/models) works.

## Set it up

1. Install the SDK: `pip install openai`.
2. Create the client with zurelay’s base URL and your key.
3. Call any chat model in the catalog by its ID. `AsyncOpenAI` takes the same arguments.

## Configuration

**Chat** (`app.py`):

```python
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.zurelay.com/v1",
    api_key=os.environ["ZURELAY_API_KEY"],
)

completion = client.chat.completions.create(
    model="claude-opus-5-5",
    messages=[{"role": "user", "content": "Hello"}],
)

print(completion.choices[0].message.content)
```

**Images** (`image.py`):

```python
import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.zurelay.com/v1",
    api_key=os.environ["ZURELAY_API_KEY"],
)

result = client.images.generate(
    model="nano-banana-pro",
    prompt="A glass prism splitting white light into a rainbow",
    n=1,
)

print(result.data[0].url)
```

> **Note:** The SDK also reads `OPENAI_BASE_URL` and `OPENAI_API_KEY`, so existing code can switch with two environment variables.
