# Возврат ответа напрямую { #return-a-response-directly }

Когда вы создаёте **FastAPI** *операцию пути*, вы можете возвращать из неё любые данные: `dict`, `list`, Pydantic-модель, модель базы данных и т.д.

По умолчанию **FastAPI** автоматически преобразует возвращаемое значение в JSON с помощью `jsonable_encoder`, как описано в [JSON кодировщик](../tutorial/encoder.md){.internal-link target=_blank}.
