You can think of `APIRouter` as a "mini `FastAPI`" class.

All the same options are supported.

All the same `parameters`, `responses`, `dependencies`, `tags`, etc.

/// tip

In this example, the variable is called `router`, but you can name it however you want.

Sie müssten beispielsweise einem Client sagen:

* Dass er nicht die notwendigen Berechtigungen hat, eine Aktion auszuführen.
* Dass er zu einer Ressource keinen Zugriff hat.
* Dass die Ressource, auf die er zugreifen möchte, nicht existiert.
