# Django Ninja Fast Declarative REST APIs with Pydantic

Develops REST APIs with Django Ninja: NinjaAPI instance, Schema definitions, router modularization, async endpoint handlers (async def), query/path/body annotations, and seamless Django ORM integration.

## When to Invoke
Invoke this skill whenever you need to:
- write django ninja api
- django ninja pydantic schema
- async endpoint django ninja

## Execution SOP & Rules
1. Initialize API: api = NinjaAPI(title='Store API', version='1.0.0') in urls.py.
2. Define schemas: class UserOut(Schema): id: int, email: str.
3. Create route: @api.get('/users', response=list[UserOut]) def list_users(request): return User.objects.all().
4. Open /api/docs to inspect automatically generated interactive Swagger documentation.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
