Ele também declara novamente `id: int`. Ao fazer isso, estamos fazendo um **contrato** com os clientes da API, para que eles possam sempre esperar que o `id` estará lá e será um `int` (nunca será `None`).

Ayrıca `id: int` alanını yeniden tanımlar. Bunu yaparak API client’larıyla bir **contract** (sözleşme) oluşturmuş oluruz; böylece `id` alanının her zaman var olacağını ve `int` olacağını (asla `None` olmayacağını) bilirler.

The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

## Check it { #check-it }

Use it the same way you would use the `FastAPI` class:

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[6,11,16] title["app/routers/users.py"] *}

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

All the same options are supported.

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