Build a Crypto Price Tracker

// 1. Get current BTC price from Coinbase
const priceRes = await fetch('https://api.coinbase.com/v2/prices/BTC-USD/spot');
const { data: { amount: currentPrice } } = await priceRes.json();

// 2. Get 7-day history from CryptoCompare
const histRes = await fetch(
  'https://min-api.cryptocompare.com/data/v2/histoday?fsym=BTC&tsym=USD&limit=7&api_key=YOUR_API_KEY'
);
const { Data: { Data: history } } = await histRes.json();
const weekAgoPrice = history[0].close;
const change = ((currentPrice - weekAgoPrice) / weekAgoPrice * 100).toFixed(2);

// 3. Get crypto news
const newsRes = await fetch(
  'https://gnews.io/api/v4/search?q=bitcoin+cryptocurrency&token=YOUR_API_KEY&max=5'
);
const { articles } = await newsRes.json();

// 4. Display dashboard
console.log(`BTC: $${currentPrice} (${change}% 7d)`);
articles.forEach(a => console.log(`- ${a.title}`));
