El resultado es que, en nuestra aplicación, cada una de las *path operations* del módulo `admin` tendrá:

* El prefix `/admin`.
* El tag `admin`.
* La dependencia `get_token_header`.
* La response `418`. 🍵

Pero eso solo afectará a ese `APIRouter` en nuestra aplicación, no en ningún otro código que lo utilice.

Those worker processes would be the ones running your application, they would perform the main computations to receive a **request** and return a **response**, and they would load anything you put in variables in RAM.

            params.put("Requested Time", FessFunctions.formatDate(e.getRequestedAt()));
            params.put("Query Time", toNumberString(e.getQueryTime()));
            params.put("Response Time", toNumberString(e.getResponseTime()));
            params.put("Hit Count", toNumberString(e.getHitCount()));
            params.put("Offset", toNumberString(e.getQueryOffset()));

Esos worker processes serían los que ejecutan tu aplicación, realizarían los cálculos principales para recibir un **request** y devolver un **response**, y cargarían cualquier cosa que pongas en variables en RAM.

### Check it { #check-it }

Open your browser at <a href="http://127.0.0.1:8000/items/5?q=somequery" class="external-link" target="_blank">http://127.0.0.1:8000/items/5?q=somequery</a>.

You will see the JSON response as:

```JSON
{"item_id": 5, "q": "somequery"}
```

You already created an API that:

* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`.
