title: Get Current Firestore API Calls
body: <p>Is there a way to fetch (via iOS) the current number of <strong>Firestore API requests</strong> an app has used for the day / week / billing cycle?</p>
  
  <hr>
  
  <p>I'm trying to see if I can fetch this value to display it to the user. I know some database services offer this as a service in order to determine how many requests are remaining.</p>
