# Path-параметры и валидация числовых данных { #path-parameters-and-numeric-validations }

Так же, как с помощью `Query` вы можете добавлять валидацию и метаданные для query-параметров, так и с помощью `Path` вы можете добавлять такую же валидацию и метаданные для path-параметров.

## Импорт `Path` { #import-path }

Сначала импортируйте `Path` из `fastapi`, а также импортируйте `Annotated`:
