All the prices are denominated in USD. You can fetch price data for BTC, ETH, AR, EUR and any other of  100+ supported tokens​
Price data format
  {
    value: 123.23, // Number: Price value in USD
    timestamp: 1617146511173, // Number: Timestamp (ms) for price
    provider: "I-5rWUehEv-MjdK9gFw09RxfSLQX9DIHxG614Wf8qo0", // String: Provider arweave address

    source: {"coingecko": 123,"sushiswap": 123.23,"uniswap": 123.35}, // Object: Prices from different sources

Fetch price using promises
  // As async/await is only a syntactic sugar on Javascript
  // Promises you can use them in a "standard" way
  const price = redstone.getPrice("AR").then((price) => {
    console.log(price.value); // latest price value for AR token
  });
Get the latest prices for multiple tokens
To fetch prices for multiple tokens use the getPrice method and pass an array with a subset of supported tokens.
const prices = await redstone.getPrice(["BTC", "ETH", "AR", "EUR"]);
​
console.log(prices); // Example output below
/*
{
  "BTC": {
    value: 58953.39,
    timestamp: 1617152802779,
    ...
  },
  "ETH": {
    value: 1856.75,
    timestamp: 1617152802779,
    ...
  },
  ...
}
*/
​
​
console.log(prices["BTC"].value); // latest price value for BTC
console.log(prices["ETH"].value); // latest price value for ETH
console.log(prices["AR"].value); // latest price value for AR
