I am currently using the @Solana/web3.js framework and want to grab the current price for Solana in order to convert a user's balance to USD .etc.
The @solana/web3.js module currently concerns itself solely with interacting with native Solana programs as well as giving the tools to interact with the Solana blockchain via the RPC.
I recommend using CoinGecko's API to find the current USD value of SOL and other tokens.
Here is a client side example, notice the url params
ids=solana vs_currencies=usd
var url = "https://api.coingecko.com/api/v3/simple/price?ids=solana&vs_currencies=usd";
var xhr = new XMLHttpRequest();
xhr.open("GET", url);
xhr.setRequestHeader("accept", "application/json");
xhr.onreadystatechange = function() {
if (xhr.readyState === 4) {
console.log(xhr.status);
console.log(xhr.responseText);
}
};
xhr.send();
