Da der Pfad jeder *Pfadoperation* mit `/` beginnen muss, wie in:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

... darf das Präfix kein abschließendes `/` enthalten.

Das Präfix lautet in diesem Fall also `/items`.

Wir können auch eine Liste von `tags` und zusätzliche `responses` hinzufügen, die auf alle in diesem Router enthaltenen *Pfadoperationen* angewendet werden.
