## Request Body

Includes all standard OpenAI fields (`model`, `messages`, `temperature`, etc.).

<ParamField body="stream" type="boolean" default="false">
  Whether to stream the response.
</ParamField>

## Response

Returns a standard OpenAI chat completion object or stream.

    "model": "gpt-4",
    "messages": [{"role": "user", "content": "Find me some cool shirts"}]
  }'
```
