# Biconomy Exchange API
> Live spot market data from Biconomy, 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, 24h high/low, 24h change and base/quote volume; rank every spot market for a quote currency (USDT, BTC, ETH…) by 24h turnover; list the tradable pairs with their base, quote and precision; or pull live order-book depth with the real best bid/ask and running spread. Markets are addressed as BTC_USDT, with base and quote either side of the underscore. This is the Biconomy 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.
