I personally think having "localhost:8080" is easier for people that are just starting since it makes it a no-brainer on how to use the application (the example we have in usage makes it in a way where localhost:8080 works.) If we end up changing it to https://yourdomain.something, then we should change it everywhere - which will help regarding consistency.

P.S.: /api/v1/preview is another endpoint we can add to the http-requests/rest-api.http file, if you want to add a simple test there :)

I can try to write the test, but is it being used? (the http ones)
