Stooq is a Poland-based financial data platform offering free access to historical and current market data for global equities, indices, currencies, cryptocurrencies, commodities, bonds, and economic indicators. Data is delivered as CSV via a simple REST-style URL interface at https://stooq.com/q/d/l/ using query parameters for ticker symbol, date range, and interval. As of early 2026 an API key (obtained via CAPTCHA on the site) is required. A known daily request quota applies; exceeding it returns an "Exceeded the daily hits limit" message. Bulk point-in-time snapshots of the full database (12,000+ securities) are also available as ZIP-compressed CSVs from https://stooq.com/db/h/.
