What is FastAPI?

A modern, high-performance Python web framework for building APIs with automatic OpenAPI documentation and type validation.

FastAPI leverages Python type hints for automatic request validation, serialization, and API documentation. It is built on Starlette (ASGI) and Pydantic (data validation), achieving performance comparable to Node.js and Go.

Features include automatic Swagger/ReDoc documentation, dependency injection, OAuth2/JWT support, WebSocket support, and async/await native support. FastAPI is one of the fastest-growing Python frameworks.
