title: Proximity Beacon API vs Android Beacon Library?
body: <p>I'm new with the beacon technology and I have some doubts.</p>
  
  <ol>
  <li>What is the difference (who is better) between the <a href="https://developers.google.com/beacons/proximity/guides?hl=en" rel="noreferrer">Proximity Beacon API</a> vs <a href="http://altbeacon.github.io/android-beacon-library/index.html" rel="noreferrer">Android Beacon Library</a>?</li>
  <li>Proximity Beacon API is completely free? I was searching and I saw in the Google Developer Console that this API have a limit of request per day (1,000,000 request/day). I tried to search what is the quota if I spend that amount but I didn't find nothing. Android Beacon Library have a request per day limit?</li>
  </ol>
  
  <p>Until now I'm going to use the Eddystone format, so, both of them support Eddystone. </p>
  
  <p>Thanks</p>
