title: Who pays the bill for Bing Maps API calls?
body: <p>I reference this <a href="http://msdn.microsoft.com/en-us/library/ff859477.aspx" rel="noreferrer">MSDN resource on Bing Maps</a> on Bing Maps API usage reports.<br>
  As developers we usually register for Bing Maps key and embed it within wp7 apps when using Bing Maps controls. I happen to use this API WS: <code>ReverseGeocode</code>, which is billable API.<br>
  Will I pay the bill as developer?</p>
