Kylin security is based on basic access authorization, if you want to use API in your javascript, you need to add authorization info in http headers.

Example on Query API.

$.ajaxSetup({
      headers: { 'Authorization': "Basic eWFu**********X***ZA==", 'Content-Type': 'application/json;charset=utf-8' } // use your own authorization code here
    });
    var request = $.ajax({
       url: "http://hostname/kylin/api/query",
       type: "POST",
       data: '{"sql":"select count(*) from SUMMARY;","offset":0,"limit":50000,"acceptPartial":true,"project":"test"}',
       dataType: "json"
    });
    request.done(function( msg ) {
       alert(msg);
    }); 
    request.fail(function( jqXHR, textStatus ) {
       alert( "Request failed: " + textStatus );
  });
