Does Percussion offered "By The Numbers" API thing?

Since we’re growing Percussion users, I thought this page http://openscholar.harvard.edu/ is incredibly awesome. However, this section “By The Numbers” seems to be API-related. Is there something we can do for Percussion? I am not sure how they do that? 

Hi Aaron - thanks for the question, much appreciated - let us follow up and we will get back to you- have a great day thanks again

Any progress on this?
