# Renvoyer directement une réponse

Lorsque vous créez une *opération de chemins* **FastAPI**, vous pouvez normalement retourner n'importe quelle donnée : un `dict`, une `list`, un modèle Pydantic, un modèle de base de données, etc.

Par défaut, **FastAPI** convertirait automatiquement cette valeur de retour en JSON en utilisant le `jsonable_encoder` expliqué dans [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.
