@lye So about the cache times... you said it'd just be the cache headers. However, I just tested it with the /account/wallet endpoint, which does not have a cache header at all, but it took exactly 10 minutes to update to the value ingame after a change.
Interestingly it was way faster after changing maps

I will do what I can but turnaround will be slow and my involvement w/ anything non-JS will be non-existant
