Puedes declarar el tipo utilizado para el response anotando el **tipo de retorno** de la *path operation function*.

Puedes utilizar **anotaciones de tipos** de la misma manera que lo harías para datos de entrada en **parámetros** de función, puedes utilizar modelos de Pydantic, lists, diccionarios, valores escalares como enteros, booleanos, etc.
