In some special use cases (probably not very common), you might want to **restrict** the cookies that you want to receive.

#### Forbid Extra Query (Cookie, Header) Parameters

Use Pydantic models to restrict extra values for `Query` parameters (also applies to `Header` and `Cookie` parameters).

To achieve it, use Pydantic's `model_config = {"extra": "forbid"}`:

```python
from typing import Annotated, Literal
