Wiener Börse (ATX) API
Live Austrian equity data from the Wiener Börse (Vienna Stock Exchange): real-time quotes for any listed stock by ticker (price, % change, intraday OHLC, volume, market cap in EUR), a ranking screener for gainers, losers, most-active and top market-cap local primary listings, and the Vienna index family (ATX, ATX Prime and ATX Five). Foreign depositary receipts are filtered out so you get only genuine Austrian companies such as Erste Group, VERBUND, OMV, Raiffeisen Bank and BAWAG.
