# Eine Response direkt zurückgeben { #return-a-response-directly }

Wenn Sie eine **FastAPI** *Pfadoperation* erstellen, können Sie normalerweise beliebige Daten davon zurückgeben: ein `dict`, eine `list`, ein Pydantic-Modell, ein Datenbankmodell, usw.

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

# Devolver una Response Directamente { #return-a-response-directly }

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}.
