What is FastAPI?
FastAPI is a modern, high-performance Python web framework for building APIs. Created by Sebastian Ramirez, it's one of the fastest Python frameworks available, on par with Node.js and Go.
FastAPI leverages Python type hints to provide automatic validation, serialization, and documentation. It generates OpenAPI (Swagger) documentation automatically, making API development faster and more reliable.
