# Modelos de Parámetros de Header

Si tienes un grupo de **parámetros de header** relacionados, puedes crear un **modelo Pydantic** para declararlos.

Esto te permitirá **reutilizar el modelo** en **múltiples lugares** y también declarar validaciones y metadatos para todos los parámetros al mismo tiempo. 😎

/// note | Nota

Esto es compatible desde la versión `0.115.0` de FastAPI. 🤓
