# 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}.

    * `200` es el código de estado por defecto, lo que significa que todo estaba "OK".
    * Otro ejemplo sería `201`, "Created". Comúnmente se usa después de crear un nuevo registro en la base de datos.
    * Un caso especial es `204`, "No Content". Este response se usa cuando no hay contenido para devolver al cliente, por lo tanto, el response no debe tener un body.
