I think you need a dashboard with animated graphs (preferably in bright colors on a dark background with thin text that has just enough color contrast to indicate that there's text there at all) to help track KPIs. With push notifications if even/odd distributions veer outside of a user-defined threshold, which is cunningly defined as an index value with a more impressive sounding name and handy three letter abbreviation.
That should really help distinguish yourself in this hotly contested market space.
It appears that the API is unversioned, which concerns me as my company is very future-looking and will need to support numbers as they modernize. How will you handle version migrations?
