В этом примере, у нас есть 3 параметра запроса:

* `needy`, обязательный `str`.
* `skip`, типа `int` и со значением по умолчанию `0`.
* `limit`, необязательный `int`.

Вы можете использовать класс `Enum` также, как ранее применяли его с [Path-параметрами](path-params.md#_7){.internal-link target=_blank}.
