I recently had the idea of making a SocialBlade equivalent for PMC accounts, which would give you ratings on how well your packs are doing, and how good of an account you have!
But to do this sort of thing, you would need to either webscrape (which is shady and not that great), or use an API (which as far as I know, doesn't exist).

I did find the file https://planetminecraft.com/api/ but that seems to just give a uuid or something.
The API could be used in javascript or python to retrieve info such as how many diamonds, views, downloads something has by name or URL, etc.
