Why does my API call work in chrome but not in my code?
As mentioned in other answer, there is CORS issue. So you can try with proxyURL from client side as below,
$(document).ready(function() {
var url = 'https://api.binance.com/api/v1/ticker/price?symbol=LTCBTC';
const proxyURL = "https://cors-anywhere.herokuapp.com/";
$.getJSON(proxyURL + url, function(playerData) {
console.log(playerData);
});
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>Hope it helps.
