# Modelos de Parâmetros do Cabeçalho

Se você possui um grupo de **parâmetros de cabeçalho** relacionados, você pode criar um **modelo do Pydantic** para declará-los.

Isso vai lhe permitir **reusar o modelo** em **múltiplos lugares** e também declarar validações e metadadados para todos os parâmetros de uma vez. 😎

/// note | Nota

Isso é possível desde a versão `0.115.0` do FastAPI. 🤓
