            var api = {
               "assync":true,
               "scrossDomain": true,
               "url":"https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd&include_market_cap=true&include_24hr_vol=true&include_24hr_change=true&precision=2",
               "method":"GET",
               "headers":{}}
          
          $.ajax(api).done(function (response){btc.innerHTML = response.bitcoin.usd;});
      
         </script>
    </body> 
</html>

It returns me "NaN". How can I convert it to 2 decimals? Or I can´t convert numbers from api in js? If I try to put some fixed value, it works. But with api it doesn´t.

Change:

var api = { "assync":true, …

To „async“: true

I think you ll get the right decimal number. Otherwise use.toFixed(2) but it converts it to a string which you can convert to a number with +.
