Otra gran funcionalidad necesaria por las APIs es la validación de datos, asegurarse de que los datos sean válidos, dados ciertos parámetros. Por ejemplo, que algún campo sea un `int`, y no algún string aleatorio. Esto es especialmente útil para los datos entrantes.

Sin un sistema de validación de datos, tendrías que hacer todas las comprobaciones a mano, en código.

CMD fastapi run app/main.py --port 80
```

Asegúrate de siempre usar la **forma exec** para garantizar que FastAPI pueda cerrarse de manera adecuada y que [los eventos de lifespan](../advanced/events.md){.internal-link target=_blank} sean disparados.
