`Header`, `Path`, `Query` ve `Cookie`'nin sağladıklarına ek olarak küçük bir ekstra işlevsellik sunar.

Standart header'ların çoğu, "hyphen" karakteri (diğer adıyla "minus symbol" (`-`)) ile ayrılır.

Ancak `user-agent` gibi bir değişken adı Python'da geçersizdir.

Bu yüzden, default olarak `Header`, header'ları almak ve dokümante etmek için parametre adlarındaki underscore (`_`) karakterlerini hyphen (`-`) ile dönüştürür.

from typing import Annotated

from fastapi import FastAPI, Header

app = FastAPI()


@app.get("/items/")
async def read_items(user_agent: Annotated[str | None, Header()] = None):

			if e.lockRetention != nil && e.lockRetention.LockEnabled {
				event = Event{}
			} else {
				// No need to evaluate remaining versions' lifecycle
				// events after DeleteAllVersionsAction*
				events[i] = event
				break loop
			}

		case DeleteVersionAction, DeleteRestoredVersionAction:
			// Defensive code, should never happen
			if obj.VersionID == "" {

Cada “scope” é apenas uma string (sem espaços).

Normalmente são usados para declarar permissões de segurança específicas, por exemplo:

* `users:read` ou `users:write` são exemplos comuns.
* `instagram_basic` é usado pelo Facebook e Instagram.
* `https://www.googleapis.com/auth/drive` é usado pelo Google.
