I'm thinking of building a small powershell/.Net app that can do data usage projections and calculations, so was wondering if there is an API exposed already to load usage information.

Basically, I want it to track how I am with my usage up until now, from the start of the month against my cap, and then also tell me how much data I can download per day/per week, in order to stay within my data limit.


FYI, I'm not looking for a "why don't you go unlimited?" response, so please don't reply with that.
