Hello.
It used to be somehow easier to get json files by reference, now it feels like something has changed.
Does not want to work, does not transmit anything, information 0 (zero), via console.log() and via alert()
sends NOTHING. Not even undefanted. Full zero. What is the problem and why it stopped working I do not understand.
If there is any other way - tell me. PHP is not suitable.
Here is the code itself that stopped working:

<!doctype>
<html lang="ru">
  <head>
    <meta charset="utf-8">
    <title>Веб-страница</title>
    <script>
       function loadJSON(callback) {   

        var xobj = new XMLHttpRequest();
        xobj.overrideMimeType("application/json");
        xobj.open('GET', 'https://bittrex.com/api/v1.1/public/getmarketsummary?market=BTC-GBG', true);
        xobj.onreadystatechange = function () {
            if (xobj.readyState == 4 && xobj.status == "200") {
            callback(xobj.responseText);
            }
        };
        xobj.send(null);  
       }
      function init() {
       loadJSON(function(response) {
        var actual_JSON = JSON.parse(response);
        document.getElementById("data").innerHTML = actual_JSON.result[1].MarketName + " / " + actual_JSON.result[1].BaseVolume;
       });
      }
    </script>		
  </head>
  <body>
    <h1>Заголовок</h1>
    <div id="data"></div>
  </body>
</html>

You need to climb into bittrex and most likely add the url or ip from which you send the request so that the server gives you the Access-Control-Allow-Origin header: https://yourdomain
Otherwise, you are unlikely to succeed with js. At least through a browser
