Here is a code sample showing how to use this service programmatically.

In PHP, for example, you might access this IP Address Locator service like this:

   function getIP() {
      foreach (array('HTTP_CLIENT_IP','HTTP_X_FORWARDED_FOR','HTTP_X_FORWARDED',
                     'HTTP_X_CLUSTER_CLIENT_IP','HTTP_FORWARDED_FOR','HTTP_FORWARDED',
                     'REMOTE_ADDR') as $key) {
         if (array_key_exists($key, $_SERVER) === true) {
            foreach (explode(',', $_SERVER[$key]) as $ip) {
               if (filter_var($ip, FILTER_VALIDATE_IP) !== false) {
                  return $ip;
               }
            }
         }
      }
   }

   $json = file_get_contents('https://secure.geobytes.com/GetCityDetails?key=7c756203dbb38590a66e01a5a3e1ad96&fqcn=' . getIP());
   $data = json_decode($json);
   echo '<b>'. getIP() .'</b> resolves to:
'. var_dump($data);
