2. Developer Experience: Automatic interactive API documentation (Swagger UI at /docs and ReDoc at /redoc) is generated from your code. No more writing separate API documentation.
3. Reduced Bugs: Using Python type hints, FastAPI validates request and response data, providing clear errors and auto-completion in IDEs.
