|
FastAPI is a modern, *high-performance* web framework for building APIs with Python.
|
|
It's designed to be **easy to use**, fast to code, and ready for production.
|
|
Key features include **automatic data validation** (using Pydantic), **dependency injection**, and **automatic interactive API documentation** (OpenAPI and Swagger UI).
