Paid against free › Trading & Investing › Market Data & Connectivity › Market Data APIs · Markets and trading on Repo Radar
A market data API delivers stock, option, futures, currency and crypto prices to your code, live or historical. The paid side ranges from cheap all-rounders priced by requests per minute (Alpha Vantage, Twelve Data, Financial Modeling Prep, EODHD, Tiingo) through developer-focused US feeds (Massive, formerly Polygon.io) to exchange-depth tick data (Databento) and the enterprise feeds banks license (Bloomberg). The open-source side is mostly client libraries for those vendors, plus free tools that read Yahoo Finance, public Chinese market sites or crypto exchange feeds directly.
