You can use this JavaScript module to get historical prices for cryptocurrencies / blockchain assets.
npm i --save @exodus/prices
parameters:
fromSym:<string>: An asset or fiat string symbol.toSym:<string>: An asset or fiat string symbol.date:<Date>: An instance ofDaterepresenting some date in the past.
Example:
global.fetch = require('node-fetch') // not necessary in the browser
const { fetchPrice } = require('@exodus/prices')
const t1 = new Date('2017-01-10 12:25 CST')
const btcPrice = await fetchPrice('BTC', 'USD', t1)
console.log(btcPrice.toFixed(2)) // => 903.30
const ethPrice = await fetchPrice('ETH', 'USD', t1)
console.log(ethPrice.toFixed(2)) // => 10.47- Requires
global.fetch
this depends on fetch() being defined globally.
- If you are using this in Electron, it should work without any configuration assuming it's running in the renderer process.
- If you are using this in Node.js, you will need to use
node-fetch.
-
This depends upon the cryptocompare API.
-
Granularity is only limited to daily. Thus, anytime in the day uses a simple linear interpolation between the open and close prices.
-
Occasionally cryptocompare's historical data changes. See https://github.com/ExodusMovement/audit-pricing/commit/2f9cc8cb61eb2e38983c3fee704943d67c6a9ef5 as an example.
