И она может возвращать всё, что требуется.

В этом случае, эта зависимость ожидает:

* Необязательный query-параметр `q` с типом `str`
* Необязательный query-параметр `skip` с типом `int`, и значением по умолчанию `0`
* Необязательный query-параметр `limit` с типом `int`, и значением по умолчанию `100`

И в конце она возвращает `dict`, содержащий эти значения.

## `examples` in JSON Schema - OpenAPI

When using any of:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

you can also declare a group of `examples` with additional information that will be added to their **JSON Schemas** inside of **OpenAPI**.
