Solve the challenge of building high-performance asynchronous Python APIs with FastAPI and Pydantic V2.
Create a minimal FastAPI app with a Pydantic V2 model, add a JWT login route, and expose /docs for experimentation.

Build async REST endpoints by defining Pydantic V2 models for request validation and using async def route handlers to manage concurrent I/O operations. This approach enforces strict typing while maximizing backend throughput.
Implement JWT authentication by applying Annotated dependencies to secure route paths and validate encoded tokens. This workflow protects endpoints by enforcing verified access tokens before processing requests.
Yes, you can use async SQLAlchemy to handle non-blocking database interactions within async endpoints. This integration allows your application to manage concurrent database queries efficiently without blocking the event loop.
FastAPI automatically generates OpenAPI documentation for REST endpoints, but WebSocket endpoints are not natively included in the standard OpenAPI schema. You can still build WebSocket support for real-time communication alongside documented REST routes.
Structure dependency injection using Annotated dependencies to pass authentication context, database sessions, and validation logic directly into route signatures. This method isolates business logic and enforces strict typing across secure API routes.
Use Pydantic V2 schemas to enforce strict typing and validate incoming request data before processing. This integration prevents data format errors and automatically generates the required OpenAPI documentation surface.
