Motivation

My two Android apps Metal Only and MensaUPB require some kind of online service to get their data from and - since I cannot force users to update apps easily - I wrote my own API as a wrapper to the upstream APIs provided by https://www.metal-only.de/ and https://studierendenwerk-pb.de/. That way, whenever one of these pages changes their API, I can just adapt the wrapper and keep my own API backwards-compatible so the apps themselves don’t require any updates.
