title: Why does the Google Geocoding API work without key?
body: <p>I'm reading the documentation for the Google Geocoding API, and I noticed that it <a href="https://developers.google.com/maps/documentation/geocoding/intro">says</a> that a key is required in a geocoding request, but when I do "<a href="https://maps.googleapis.com/maps/api/geocode/json?address=LosAngeles,usa">https://maps.googleapis.com/maps/api/geocode/json?address=LosAngeles,usa</a>" it gives me the expected result.</p>
  
  <p>Why is this? Is the documentation wrong? Will it start asking for the key after a certain amount of requests? Or is there something I'm not understanding?</p>
