How to get BTC current price data from Coinbase API?

Question

I am trying to get BTC current price from the following API endpoint:

https://api.coindesk.com/v1/bpi/currentprice.json

function CoinbaseBTCPrice(){
    $.ajax({
    url: "https://api.coindesk.com/v1/bpi/currentprice.json",
    success: function(bitcoinPrice){
        console.log(bitcoinPrice.bpi.USD.rate)
        }
    })
}

When I try to do this it says that the data I am looking for is undefined.

You need to parse the returned JSON string first using JSON.parse. Find out more in here.

CoinbaseBTCPrice();

function CoinbaseBTCPrice(){
    $.ajax({
    url: "https://api.coindesk.com/v1/bpi/currentprice.json",
    success: function(bitcoinPrice){
        console.log(JSON.parse(bitcoinPrice).bpi.USD.rate)
        }
    })
}

For shorter version, you can you $.getJSON instead.

$.getJSON("https://api.coindesk.com/v1/bpi/currentprice.json", function(currentPriceInfo){
  console.log(currentPriceInfo.bpi.USD.rate)
});
