# API Reference

> Endpoint reference auto-rendered from openapi.yaml

This section is auto-generated from `openapi.yaml`. Every page exposes the request shape, response shape, and a try-it-now playground (use your `sk_test_` key).

## Source of truth

The OpenAPI spec in this repo is **regenerated from the live FastAPI app**. Do NOT hand-edit `openapi.yaml`. Run the refresh script after each backend release:

```bash theme={null}
python scripts/refresh-openapi.py
```

If a doc page disagrees with `openapi.yaml`, the spec is the source of truth. Fix the backend or fix the spec, then regenerate the docs.
