```

Como el path de cada *path operation* tiene que empezar con `/`, como en:

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

...el prefijo no debe incluir un `/` final.

Así que, el prefijo en este caso es `/items`.

{!../../docs_src/bigger_applications/app/routers/items.py!}
```

Como o caminho de cada *operação de rota* deve começar com `/`, como em:

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

...o prefixo não deve incluir um `/` final.

Então, o prefixo neste caso é `/items`.
