Stablecoins API

healthy 3,435 Subscribers

Live stablecoin supply, peg and dominance data across the whole crypto ecosystem as an API, streamed from the DefiLlama stablecoins feed. For every tracked stablecoin: its circulating supply in USD, current price and peg deviation, peg type and mechanism (fiat-backed, crypto-backed or algorithmic), the chains it lives on, and its share of the total stablecoin market. List the biggest stablecoins with their dominance, drill into one for its peg health and per-chain breakdown, see total stablecoin supply per chain, or search. Built for crypto, risk and dashboard apps. Live, no key. Distinct from TVL, price and yield APIs — this is the stablecoin supply and peg surface.

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.

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.
