A request body is data sent by the client to your API. Next, we defined a function called fetchTodos to retrieve todos from the backend asynchronously Note: You can mix def and async def in your path operation functions as much as you need and define each one using the best option for you. The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values. 7+ type hints to provide an efficient and developer-friendly experience for building OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation). The Hero class is very similar to a Pydantic model (in fact, underneath, it actually is a Pydantic model). 4 There is a Makefile with some useful commands to help you get started. Under the hood, FastAPI can effectively handle both async and sync I/O operations. This REST API serves as an ERP system for a car shop. Query.
