+FastAPI<sup>[View Repo](https://github.com/fastapi/fastapi/tree/628c34e0cae200564d191c95d7edea78c88c4b5e/fastapi)</sup> 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).
