A simple NPM package for querying the current price of cryptocurrencies.

Install with npm:

npm install crypto-price-query

First, you need to import crypto-price-query:

const getCoinPrices = require('crypto-price-query'); Then, you can use the getCoinPrices function to query the price of one or more cryptocurrencies:

getCoinPrices(['bitcoin', 'ethereum'], 'usd')
  .then(prices => console.log(prices))
  .catch(error => console.error(error));

This will return an object with the coin names as keys and their corresponding prices as values like

{
  bitcoin: { usd: 62064 },
  ethereum: { usd: 3411.79 }
}
