FastAPI best practices and conventions for clean, modern API development. \n \n Use Annotated for all parameter and dependency declarations to maintain type safety, reusability, and compatibility with other contexts \n Declare return types or response models on path operations to enable automatic validation, filtering, serialization, and OpenAPI documentation \n Use async def only when calling async code with await ; default to regular def for blocking operations to avoid event loop blocking \n
