por padrão, o FastAPI irá verificar cada item dentro do dicionário e garantir que ele seja serializável para JSON, utilizando o mesmo[Codificador Compatível com JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado no tutorial. Isso permite que você retorne **objetos abstratos**, como modelos do banco de dados, por exemplo.

Mas se você tem certeza que o conteúdo que você está retornando é **serializável com JSON**, você pode passá-lo diretamente para a classe de resposta e evitar...
