# Retornando uma Resposta Diretamente

Quando você cria uma *operação de rota* no **FastAPI** você pode retornar qualquer dado nela: um dicionário (`dict`), uma lista (`list`), um modelo do Pydantic ou do seu banco de dados, etc.

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}.
