API integration

when i want to integrate this API code :

$.get(
http://api.labsmobile.com/get/balance.php”,
{username : ‘raoulalobo15011984@yahoo.fr’, password : ‘rb27vm95’},
function(data) {
alert('page content: ’ + data);
}
);

i have this message :
XMLHttpRequest cannot load http://api.labsmobile.com/get/balance.php?username=raoulalobo%40yahoo.fr&password=rb27vm95. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:3000’ is therefore not allowed access.

how can i fix it please
