## Параметри Заголовків з Використанням Pydantic Model

Оголосіть потрібні **параметри заголовків** у **Pydantic моделі**, а потім оголосіть параметр як `Header`:

{* ../../docs_src/header_param_models/tutorial001_an_py310.py hl[9:14,18] *}

FastAPI буде витягувати дані для кожного поля з заголовків у запиті та передавати їх у створену Вами Pydantic модель.
