# Deepcoin Exchange API
> Live spot market data from Deepcoin, a global 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 high/low, 24h change and base/quote volume; rank every spot market for a quote currency (USDT, BTC, ETH…) by 24h quote volume; list the tradable instruments with their base, quote and tick/lot size; or pull live order-book depth with the running spread. Markets are addressed OKX-style as BTC-USDT, with base and quote either side of the hyphen. This is the Deepcoin venue specifically — a distinct global exchange feed, separate from the other exchange APIs in the catalogue, so cross-venue arbitrage and price-discovery workflows can read each book on its own terms.
