Meteor Access Denied when calling google's Geocoder API

Question

While calling geocode API of google maps, i am getting Access Denied. It strange since i can call LatLng and it works fine. What am i missing ? I also have my key and everything defined.

GoogleMaps.load({ v: '3', key: 'xyz key', libraries: 'geometry,places' });

     var geocoder = new google.maps.Geocoder();
      geocoder.geocode({
        'address': '1234 street'
      }, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          console.log(results[0].geometry.location);
        } else {
          console.log("some err " + results + " status " + status);
        }
      });
