"_We adopted the **FastAPI** library to spawn a **REST** server that can be queried to obtain **predictions**. [for Ludwig]_"

This is something that you have to do yourself in your code, and make sure you use those JSON keys.

It's almost the only thing that you have to remember to do correctly yourself, to be compliant with the specifications.

For the rest, **FastAPI** handles it for you.

///

## Update the dependencies

Now we are going to update our dependencies.

We want to get the `current_user` *only* if this user is active.

Das müssen Sie selbst in Ihrem Code tun und sicherstellen, dass Sie diese JSON-Schlüssel verwenden.

Es ist fast das Einzige, woran Sie denken müssen, es selbst richtigzumachen und die Spezifikationen einzuhalten.

Den Rest erledigt **FastAPI** für Sie.

///

## Die Abhängigkeiten aktualisieren

Jetzt werden wir unsere Abhängigkeiten aktualisieren.

Wir möchten den `current_user` *nur* erhalten, wenn dieser Benutzer aktiv ist.
