title: Price per request in Google Analytics API
body: <p>I'm looking for prices of additionnal API calls within Google Analytics.
  In the developers console, I can enter my billing information, but before, I'd like to find a price table somewhere.
  I know that the free quota is 50 000 requests per month, I know we can ask for an extension, but I need much more and I'm ready to pay. The only question is : what does it cost ?
  Thanks !</p>
