Not bad! I can think of some uses for this (although it's been a while since I created any topic that can use it).
Thank you. I will create the API documentation soon and create more API endpoints.
Question: how does it work with updates: are they real-time? And if so: does the forum proxy not cache the old version?
Yes, real time. However, there are no updates.
Once you make the request, the old image is deleted and a new one is created. Every time you reload the page (call the API again) a new image is generated with the newest blockchain and price data.
So, the image is always updated. There is no cache.
