You can utilize the Object.keys method in Javascript. https://developer.mozilla.org/de/docs/Web/JavaScript/Reference/Global_Objects/Object/keys

var keys = Object.keys(response.data.players);
var player = response.data.players[keys[0]];

If you want to get a random player you can use this code:

function getRandomInt(max) {
  return Math.floor(Math.random() * Math.floor(max));
}

var keys = Object.keys(response.data.players);
var player = response.data.players[keys[getRandomInt(keys.length)]];
