defecto, FastAPI inspeccionará cada elemento dentro y se asegurará de que sea serializable como JSON, usando el mismo [Codificador Compatible con JSON](../tutorial/encoder.md){.internal-link target=_blank} explicado en el tutorial. Esto es lo que te permite devolver **objetos arbitrarios**, por ejemplo, modelos de bases de datos.

Pero si estás seguro de que el contenido que estás devolviendo es **serializable con JSON**, puedes pasarlo directamente a la clase de response y evitar la sobrecarga...
