Örnek bir kod bırakıyorum:
<html>

<body>

<div class="div-block-3">
  <div class="text-block-2"><span class="currency-title">USD</span> <span class="currency-symbol">$</span><strong id="BTCUSDT" class="rates"></strong></div>
</div>

<script>
function load() {
    var url_base = "https://api.binance.com/api/v3/ticker/price?symbol="
    var elements = document.getElementsByClassName('rates');
    for (var i = 0; i < elements.length; i++) {

        var id  = elements[i].id;
        var url = url_base + id;
        var ourRequest = new XMLHttpRequest();
        ourRequest.open('GET', url, true);

        ourRequest.onload = function () {
            console.log(this.responseText);

            var obj = JSON.parse(this.responseText);
            document.getElementById( obj.symbol ).innerHTML = obj.price;
        };
        ourRequest.send();
    }
}
window.onload = load;
</script>
</body
