CEO/Co-Founder here. If you have additional questions let me know. We will be launching the beta on 1/15 so please sign up using the form on the site. The beta will have some features that include pulling usage information from the APIs you use including private APIs. Next phase will include the ability to see cost so you can look at different APIs to see if you are using the one that is the most cost effective. Then we'll be moving onto giving you the ability to switch APIs on the fly.
