Trying to fetch details from an api url. Things worked well without "-" in std-detail but with "-" its showing **Error is ReferenceError: Can't find variable: detail. std-detail is the object and rest are the attributes

var total = document.getElementById("tot");
var nam = document.getElementById("fnane");
var rol = document.getElementById("roll");


var livefeed = {
    "async": true,
    "scroosDomain": true,
    "url": "https://api.xxxx.in/api/v80/simple/details?ids=**std-detail**&vs_class=tenth&include_fname=true&include_lname=true&include_roll=true",

    "method": "GET",
    "headers": {}
    
}

$.ajax(livefeed).done(function (response){
    console.log(response);
   total.innerHTML = response.std-detail.tenth;

  
});

Error is ReferenceError: Can't find variable: detail std-detail is the object and rest are attributes
