Eso es lo que resolveremos, vamos a cargar el modelo antes de que los requests sean manejados, pero solo justo antes de que la aplicación comience a recibir requests, no mientras el código se está cargando.

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.
