Google map integration issue : "This site has exceeded its daily quota for

[Abhi_6]

I am getting the longitude and latitude from AJAX and giving me more 120 on every page load. Marking the result locations into google map and using browser key. It was working fine, but suddenly it stopped working and getting 'This site has exceeded its daily quota for maps. If you are the creator of this site, please visit the documentation to learn more' error plus page hangs. It has been more than 24 hours, but the problem remains same. I tried to found out the solution but no luck and I changed new API key.

JS files:

<script src="http://open.mapquestapi.com/sdk/js/v7.2.s/mqa.toolkit.js?key=my-browser-key"></script> 
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&signed_in=true&libraries=geometry"></script>

JS code:

var infowindow;

var latitude    = '51.497801';
var longitude   = '-0.065918';
var myLatlng    = new google.maps.LatLng(latitude,longitude); 
var geocoder    = new google.maps.Geocoder();
