# Bithumb Exchange API
> Live spot market data from Bithumb, South Korea's major 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, 24h open/high/low, 24h change and base/quote volume; rank every market for a payment currency (Korean won KRW, or BTC) by 24h turnover; list the tradable coins; or pull live order-book depth with the running spread. Markets are addressed COIN_PAYMENT (BTC_KRW, ETH_BTC). This is the Bithumb venue specifically — a distinct Korean-won price feed, ideal for tracking the "kimchi premium" and KRW price discovery, separate from the USD/USDT-quoted exchange APIs in the catalogue.
