For example, to declare a title metadata value for the path parameter item_id you can type:Python 3.10+ from typing import Annotated from fastapi import FastAPI, Path, Query app = FastAPI() @app.get("/items/{item_id}") async def read_items( item_id: Annotated[int, Path(title="The ...

So, I understand that the best practice to make a parameter required is to simply not assign a default value to it, for example: @app.get("/validation") async def async_root(str_param: Annotated[str, Query(min_length=3, max_length=20, pattern='^[a-zA-Z0-9]+$', description='This...
