Is there a way to use the exercise.io web api I can use to get team stats by user?

I really like exercism.io. So much so that I want to use it internally in my development house to gamify our team's skill acquisition using their data from exercism.io.

They seem to have an API in their repos. I know all the details given in the repo. But for the life of me, I can't find the URL to a public API endpoint.

It may well be that there is NON. But I am giving it a shot. Thanks.
