About

Alpha Vantage is a market data service that hands out a free API key you can use to look up stock prices, company financials, currency rates, and built-in technical indicators like moving averages. You can use it to build a personal stock dashboard that shows daily price history, to screen companies by metrics such as price-to-earnings ratio, or to pull forex rates for a currency converter. The free tier is genuinely usable for side projects, though the daily request cap is tight.
