TestCases

when I am trying to get details of all testcases using a api  https://api.zephyrscale.smartbear.com/v2/testcases, I'm getting the data but,

why I'm not getting values of a few fields like(status,priority,testScript,.......) instead I'm getting url's for that fields and I need to run that api and get the value for that field. 

For one or two its fine but, I have lot of testcases, I can't loop each and every url and get data.

Is there any way to get data directly without urls?
