Question for anyone knowledgeable about Facebook's Apps Directory

There are several sites that provide statistical information about the daily/monthly active users for various apps on Facebook, and I was wondering where this data is coming from. Check out [login to view URL] and [login to view URL] to see what I'm talking about. It seems unlikely they're requesting individual app pages (40,000+) from Facebook and scraping the data from those every day. BUT I didn't see any API calls that provide this info either. Or maybe I'm missing something obvious. Does this data live somewhere on Facebook that I'm not aware of? I'll pay for your assistance with this. ## Deliverables Text answer via email or whatever ## Platform English text
