This last path operation will have the combination of tags: `["items", "custom"]`.

And it will also have both responses in the documentation, one for `404` and one for `403`.

## The main `FastAPI` { #the-main-fastapi }

Now, let's see the module at `app/main.py`.

Here's where you import and use the class `FastAPI`.

  "durations" : [ {
    "testProject" : "nowInAndroidBuild",
    "linux" : 397,
    "windows" : 481,
    "macOs" : 403
  }, {
    "testProject" : "santaTrackerAndroidBuild",
    "linux" : 739,
    "windows" : 842,
    "macOs" : 630
  } ]
}, {

```

/// tip | Tipp

Diese letzte Pfadoperation wird eine Kombination von Tags haben: `["items", "custom"]`.

Und sie wird auch beide Responses in der Dokumentation haben, eine für `404` und eine für `403`.

///

## Das Haupt-`FastAPI`.

Sehen wir uns nun das Modul unter `app/main.py` an.

Hier importieren und verwenden Sie die Klasse `FastAPI`.
