Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

// Get daily stock prices (OHLCV)
const url = "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=IBM&apikey=YOUR_API_KEY";

const response = await fetch(url);
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();

const timeSeries = data['Time Series (Daily)'];
const latestDate = Object.keys(timeSeries)[0];
const latestData = timeSeries[latestDate];

console.log(`Latest close price for IBM: $${latestData['4. close']}`);
console.log(`Volume: ${latestData['5. volume']}`);

import requests

# Get daily stock prices (OHLCV)
url = "https://www.alphavantage.co/query"
params = {
    "function": "TIME_SERIES_DAILY",
    "symbol": "IBM",
    "apikey": "YOUR_API_KEY"
}

response = requests.get(url, params=params, timeout=30)
response.raise_for_status()
data = response.json()

time_series = data['Time Series (Daily)']
latest_date = list(time_series.keys())[0]
latest_data = time_series[latest_date]

print(f"Latest close price for IBM: ${latest_data['4. close']}")
print(f"Volume: {latest_data['5. volume']}")

curl "https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol=IBM&apikey=YOUR_API_KEY"

What Can You Build?

// Fetch stock price data
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const symbol = 'AAPL';
const response = await fetch(`https://www.alphavantage.co`, { headers });
const data = await response.json();
console.log(`${symbol} price:`, data.price || data.c || data.lastPrice);
console.log('Change:', data.change || data.dp || 'N/A');

// Fetch market overview data
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const response = await fetch(`https://www.alphavantage.co`, { headers });
const data = await response.json();
const stocks = data.results || data.data || [];
const top = Array.isArray(stocks) ? stocks.slice(0, 5) : [stocks];
top.forEach(s => {
  console.log(`${s.symbol || s.ticker}: $${s.price || s.close || 'N/A'}`);
});

// Monitor stock price and trigger alerts
const headers = { 'X-Api-Key': 'YOUR_API_KEY' };
const symbol = 'TSLA';
const threshold = 200;
const response = await fetch(`https://www.alphavantage.co`, { headers });
const data = await response.json();
const price = data.price || data.c || 0;
console.log(`${symbol}: $${price}`);
if (price > threshold) {
  console.log(`⚠️ ${symbol} is above $${threshold}!`);
}
