# Luxembourg Stock Exchange API
> Live equity market data for the Luxembourg Stock Exchange (LuxSE), one of Europe's leading listing venues, with quotes priced in EUR. Pull real-time quotes for specific listings — ArcelorMittal, ENGIE, RTL Group, Aperam, Reinet Investments and the rest of the equity board — with last price, day change percentage and absolute change, open, high, low, traded volume, market capitalisation and sector; run a ranked screener sorted by market cap, day change, volume or price; search the listings by company name; or read a market summary with the number of advancers, decliners and unchanged stocks, total market capitalisation and the day top gainer, top loser and most-active share. Distinct from other regional-exchange APIs on the marketplace — this surfaces the Luxembourg Stock Exchange equity board specifically.
