Do you also have an API so we can pull data from it and re-use / publish it?
Not yet. As I've stated in one of my earlier posts I want to provide a public API as soon as I can make a (good) living of my development. You know, I would require at least one additional powerful server for a stable public endpoint. Time will tell...
The logic for the CSI calculation is not as complicated as one might think. I've planned to publish the formula when I'm fully satisfied with it. Currently the values still vary a bit too much and I will definitely make some minor improvements in the near future. I'll keep you informed ;)
I completely understand! Do you now also understand why we have to rate-limit UA-API ourselves?
Regarding the direct API access I can understand that currently. I think a few weeks from now you will earn enough with the curation rewards to be able to order a few super machines.
Regarding your website you could create kind of an 'account info page' on steem-ua.com and load the data on page load via AJAX request. Your own domain would be added to the allowed ones in the CORS header, so that no requests from other domains will be allowed. Would be a simple and stable, working solution.
