Examples
Get the historical price for a single token
To get the historical price use the getHistoricalPrice method.
const price = await redstone.getHistoricalPrice("AR", {
  date: "2021-03-30T12:35:09", // Any convertable to date type
});
​
console.log(price.value); // AR price for specific time
The date argument must be convertable to the Date type. You may pass a date (e.g. new Date(2021-04-01)), a timestamp (e.g. 1617709771289), or just a string (e.g. 2021-04-01 or 2021-04-01T12:30:58)
Get the historical price for several tokens
To fetch the historical price for several tokens pass an array of symbols to getHistoricalPrice method.
const symbols = ["AR", "BTC", "UNI", "ETH", "EUR"];
const prices = await redstone.getHistoricalPrice(symbols, {
  date: "2021-03-30T12:35:09",
});
​
console.log(prices["BTC"].value); // BTC price for specific time
Get the historical prices in a time range
To fetch the historical prices in a time range specify token symbol as the first argument of the getHistoricalPrice method, and startDate, endDate and interval as fields of the second argument.
Currently Redstone API supports fetching historical prices in a time range only for a single token
const prices = await redstone.getHistoricalPrice("AR", {
  startDate: "2021-03-29T12:35:09",
  endDate: "2021-03-30T12:35:09",
  interval: 3600 * 1000, // 1 hour
});
​
console.log(prices); // Example output below
/*
[
  {
    value: 28.8,
    timestamp: 1617016995624,
    ...
  },
  {
    value: 28.59,
    timestamp: 1617014111705,
    ...
  },
  ...
]
*/
The startDate and endDate arguments must be convertable to Date type.
