Sadly I don't have knowledge to develope API. But I can't be the only one who has noticed that all the trackers using API have reported gem prices at same amount since Jan 11 2018. Still googling about this problem you don't get a single proper hit. To whom should this bug be informed?
I'd like to know when to buy my gems.
