## Ein weiteres Modul mit `APIRouter` { #another-module-with-apirouter }

Nehmen wir an, Sie haben im Modul unter `app/routers/items.py` auch die Endpunkte, die für die Verarbeitung von Artikeln („Items“) aus Ihrer Anwendung vorgesehen sind.

Sie haben *Pfadoperationen* für:

* `/items/`
* `/items/{item_id}`

Es ist alles die gleiche Struktur wie bei `app/routers/users.py`.
