Real-Time, Intraday & Historical Market Data API
Finance
96 APIs
Finance APIs cover stock quotes, historical prices, company filings, economic indicators, payments and bank data. Market data is where terms matter most: check delayed versus real-time quotes, exchange coverage, how much history the free tier includes, and whether you may display the data publicly. Payment and banking APIs add compliance steps and usually a sandbox before live access.
Alpha Vantage, Finnhub, Polygon and Twelve Data offer stock and forex data with an API key. FRED from the St. Louis Fed is a standard source for economic time series, and SEC EDGAR Data exposes US company filings without a key. Plaid connects apps to bank accounts, and Alpaca offers a trading API with paper trading.
