* Extra `responses`.
* `dependencies`: they all need that `X-Token` dependency we created.

So, instead of adding all that to each *path operation*, we can add it to the `APIRouter`.

{* ../../docs_src/bigger_applications/app_an_py39/routers/items.py hl[5:10,16,21] title["app/routers/items.py"] *}

As the path of each *path operation* has to start with `/`, like in:

```Python hl_lines="1"
@router.get("/{item_id}")
