FastAPI Framework

FastAPI is a modern, high-performance Python web framework designed specifically for building APIs with speed and efficiency. It leverages standard Python type hints to provide automatic data validation, serialization, and the on-the-fly generation of interactive API documentation (like Swagger UI), significantly reducing development time and potential for errors. Built upon Starlette for its asynchronous web capabilities and Pydantic for data handling, FastAPI enables developers to create robust, production-ready, and well-documented APIs quickly, with performance that is comparable to NodeJS and Go.
