# CoinMate Exchange API
> Live spot market data from CoinMate, a long-running European (Czech) crypto exchange, served straight from its public order books — no key on the data, nothing cached, nothing stored. Look up any market for its last price, best bid/ask and spread, 24h open/high/low, 24h change and base/quote volume; rank every market for a quote currency (Czech koruna CZK, euro EUR, or BTC) by 24h turnover; list the tradable pairs with their base and quote; or pull live order-book depth with the running spread. Markets are addressed BASE_QUOTE (BTC_CZK). This is the CoinMate venue specifically — a distinct Czech-koruna and euro price feed, ideal for CZK/EUR price discovery and central-European-market arbitrage, separate from the USD/USDT-quoted exchange APIs in the catalogue.
