## Resultados { #results }

Con solo esa declaración de tipo en Python, **FastAPI** hará lo siguiente:

* Leer el body del request como JSON.
* Convertir los tipos correspondientes (si es necesario).
* Validar los datos.
    * Si los datos son inválidos, devolverá un error claro e indicado, señalando exactamente dónde y qué fue lo incorrecto.
