Por padrão, o **FastAPI** irá converter automaticamente o valor do retorno para JSON utilizando o `jsonable_encoder` explicado em [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Então, por baixo dos panos, ele incluiria esses dados compatíveis com JSON (e.g. um `dict`) dentro de uma `JSONResponse` que é utilizada para enviar uma resposta para o cliente.
