    - Request parameters (path, query, body)
    - Request/response schemas with data types
    - Example requests and responses
    - Possible error codes and messages
3. **Data Models**
    - Define all data models and schemas
    - Include field descriptions and constraints
    - Show relationships between models
    - Provide example payloads
4. **Usage Examples**
    - Common use case scenarios
    - SDK and client library examples

## API Documentation Checklist

- [ ] API overview complete
- [ ] Endpoints documented
- [ ] Data models defined

## Guardrails

- Document only endpoints that exist in code; do not invent endpoints, parameters, or responses.
- Use placeholder values in examples; never expose real secrets or credentials.
