O caso mais comum seria [retornar uma Response diretamente, conforme explicado posteriormente na documentação avançada](../advanced/response-directly.md).

{* ../../docs_src/response_model/tutorial003_02_py310.py hl[8,10:11] *}

Este caso simples é tratado automaticamente pelo FastAPI porque a anotação do tipo de retorno é a classe (ou uma subclasse de) `Response`.
