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.

# Response - Cambiar Código de Estado { #response-change-status-code }

Probablemente leíste antes que puedes establecer un [Código de Estado de Response](../tutorial/response-status-code.md){.internal-link target=_blank} por defecto.

Por ejemplo, imagina que quieres devolver un código de estado HTTP de "OK" `200` por defecto.
