title: Firebase cloud functions pricing for outbound data transfer to a GAE app
body: <p>I'm developing a chat-like Firebase project with a cloud function that sends every chat message to a GAE app to index the text so that I can do text queries with the Search API.</p>
  
  <p>The Firebase function pricing page (<a href="https://cloud.google.com/functions/pricing" rel="nofollow noreferrer">https://cloud.google.com/functions/pricing</a>) says that "outbound data to other Google APIs in the same region is free".</p>
  
  <ul>
  <li>First question: Does this apply to my case? I mean, my GAE app would have the same consideration as any other Google API?</li>
  <li>Second question: In such case, how do I know both services are in the same region?</li>
  </ul>
