## The Hook

FastAPI is the Python API framework you will actually enjoy using.

## What's Good

Pydantic integration means request/response validation is declarative and automatic. OpenAPI docs generate from type hints. Async support is first-class. The dependency injection system is powerful without being magical.

## The Catch

The ecosystem assumes you will integrate pieces yourself—no batteries-included ORM or auth. Async programming has its own learning curve.

## Verdict

The Python API framework you will actually enjoy.
