Cross Domain URL

I am trying to call this URL in my javascript code:

http://api.addressify.com.au/address/autoComplete?api_key=99acd24a-1c94-49ad-b5ef-6f90d0f126b1&term=1+George+st+t&state=nsw&max_results=5

This is my javascript code:

 $.ajax({        url: 'http://api.addressify.com.au/address/autoComplete',        type: 'GET',        crossDomain: true, // enable this        data: 'api_key=99acd24a-1c94-49ad-b5ef-6f90d0f126b1&term=1+George+st+t&state=nsw&max_results=5', // or $('#myform').serializeArray()        success: function () { alert('PUT completed'); }    });

I am getting error of Cross Domain URL in console.

Any help?
