Intro to FastAPI
summary
FastAPI uses standard Python type annotations to produce automatic validation and interactive OpenAPI docs with zero boilerplate: path, query and JSON body parameters become typed function args, Pydantic handles parsing/validation and Starlette handles async serving. Complex nested lists and models validate and serialize automatically and errors return exact locations. Example app returns JSON with minimal code, runs on uvicorn and benchmarks around 15k requests per second in third‑party comparisons.
