Marketstack
Simple REST API for EOD stock prices across 70+ exchanges with 30 years of historical data
Viable option — review the tradeoffs
You need affordable end-of-day and historical stock prices from 70+ global exchanges for backtesting or basic market analysis without complex setup.
Reliable EOD data with easy JSON responses; free tier limits to 1 year history and no intraday—upgrade from $9.99/mo for 10+ years and US intraday. Per-ticker request counting can burn quota fast on bulk calls.
You want real-time or intraday stock updates integrated into trading bots or dashboards without enterprise overhead.
Solid for non-US EOD/real-time; US intraday limited to IEX source. V1 API deprecates June 2025—migrate to V2. Overages auto-charge to avoid downtime.
US Intraday Limited to IEX
Real-time/intraday data for US stocks sources only from IEX exchange, not comprehensive like premium providers. Global real-time available on higher plans but EOD-focused.
Request Quota Burns Per Ticker
Each API call for multiple symbols consumes 1 request per ticker (e.g., 5 tickers = 5 requests). Exceeding quota triggers overage fees—monitor usage and batch carefully or upgrade.
V1 API Deprecation
Version V1 endpoints deprecated after June 30, 2025—new features require V2. Existing integrations will break; plan migration now.
