Bu durumda, `q` fonksiyon parametresi isteğe bağlı olacak ve varsayılan değer olarak `None` alacaktır.

/// check | Ek bilgi

Ayrıca, dikkatinizi çekerim ki; **FastAPI**, `item_id` parametresinin bir yol parametresi olduğunu ve `q` parametresinin yol değil bir sorgu parametresi olduğunu fark edecek kadar beceriklidir.

* Do a fresh translation of this document into your desired target language (see e.g. the `translate-page` command of the `translate.py`). This will create the translation under `docs/{language code}/docs/_llm-test.md`.
* Check if things are okay in the translation.
* If necessary, improve your language specific prompt, the general prompt, or the English document.
* Then manually fix the remaining issues in the translation, so that it is a good translation.

Los parámetros `prefix`, `tags`, `responses`, y `dependencies` son (como en muchos otros casos) solo una funcionalidad de **FastAPI** para ayudarte a evitar la duplicación de código.

///

Ter `dependencies` no `APIRouter` pode ser usado, por exemplo, para exigir autenticação para um grupo inteiro de *operações de rota*. Mesmo que as dependências não sejam adicionadas individualmente a cada uma delas.
