SEMRush Ranking Tracker?

I just logged into SEM Rush it looks like they are offering a rank tracker now. Has anyone tried it? They could probably be a player in the space, their other data is pretty good... just an FYI

I love semrush but I wouldn't pay extra for a rank tracker if they use an API from them, Google are clamping down on people scraping their search results.

Raven, seomoz, ahrefs have all been told to stop or lose APIs
