* Validar que el `item_id` es del tipo `int` para requests de tipo `GET` y `PUT`.
    * Si no lo es, el cliente verá un mensaje de error útil y claro.
* Revisar si existe un query parameter opcional llamado `q` (cómo en `http://127.0.0.1:8000/items/foo?q=somequery`) para requests de tipo `GET`.
    * Como el parámetro `q` fue declarado con `= None` es opcional.

    * Verifica que tem an atributo opcional `is_offer`, que deve ser `bool`, se presente.
    * Tudo isso também funciona para objetos JSON profundamente aninhados.
* Converter de e para JSON automaticamente.
* Documentar tudo com OpenAPI, que poderá ser usado por:
    * Sistemas de documentação interativos.
    * Sistemas de clientes de geração de código automáticos, para muitas linguagens.
