# CSE Colombo Stock Exchange API > Live data from the Colombo Stock Exchange (CSE) in Sri Lanka, with no key. Read the day's market summary (turnover, share volume, trades); the headline ASPI all-share index; a full company quote with fundamentals (last price, day and 52-week range, market cap, today's volume and turnover, foreign-holding percentage and the beta versus the ASPI and S&P SL20 indices); and the day's top gainers, losers and most-active stocks. The Sri-Lanka-equities / frontier-market / foreign-holding-and-beta layer for trading dashboards, screeners and research — distinct from other exchange readers, with a fundamentals-and-risk cut.
