`response_model` recibe el mismo tipo que declararías para un campo de modelo Pydantic, por lo que puede ser un modelo de Pydantic, pero también puede ser, por ejemplo, un `list` de modelos de Pydantic, como `List[Item]`.

FastAPI usará este `response_model` para hacer toda la documentación de datos, validación, etc. y también para **convertir y filtrar los datos de salida** a su declaración de tipo.
