title: Google Geocoding API - REQUEST_DENIED
body: <p>Apparently I do not need a 'Maps API key' to use the 'Google Geocoding API' according to:</p>
  
  <p><a href="http://code.google.com/apis/maps/documentation/geocoding/index.html" rel="noreferrer">http://code.google.com/apis/maps/documentation/geocoding/index.html</a></p>
  
  <p>However, I obtain this:</p>
  
  <pre><code>{
    "status": "REQUEST_DENIED",
    "results": [ ]
  }
  </code></pre>
  
  <p>Does this mean that my IP is blocked? What can I do to overcome this?</p>
