Nehmen wir an, dass die Datei `main.py` mit Ihrer **FastAPI**-Anwendung jetzt einige andere **Pfadoperationen** hat.

Sie verfügt über eine `GET`-Operation, die einen Fehler zurückgeben könnte.

Sie verfügt über eine `POST`-Operation, die mehrere Fehler zurückgeben könnte.

Beide *Pfadoperationen* erfordern einen `X-Token`-Header.

# Devolver una Response Directamente

Cuando creas una *path operation* en **FastAPI**, normalmente puedes devolver cualquier dato desde ella: un `dict`, una `list`, un modelo de Pydantic, un modelo de base de datos, etc.

Por defecto, **FastAPI** convertiría automáticamente ese valor de retorno a JSON usando el `jsonable_encoder` explicado en [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.
