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.

EXMO Exchange API

Live spot market data from EXMO, a European/CIS 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/average and base/quote volume; rank every market for a quote currency by 24h turnover; list the tradable pairs with their base, quote and limits; or pull live order-book depth with the running spread. Markets are addressed BASE_QUOTE (BTC_UAH). This is the EXMO venue specifically — a distinct multi-fiat price feed that quotes against the Ukrainian hryvnia (UAH), Polish złoty (PLN), euro, Brazilian real and US dollar as well as USDT, ideal for UAH/PLN price discovery and Eastern-European-market arbitrage, separate from the USD/USDT-only exchange APIs in the catalogue.

Quidax Exchange API

Live spot market data from Quidax, a leading Nigerian crypto exchange, served straight from its public ticker feed — 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 (Nigerian naira NGN, USDT or USD) by 24h turnover; or list the tradable pairs with their base and quote. Markets are addressed as BTCNGN or BTC_NGN. This is the Quidax venue specifically — a distinct Nigerian-naira price feed for a high-adoption African market, ideal for NGN price discovery and Africa-market arbitrage, separate from the USD/USDT-quoted exchange APIs in the catalogue. Ticker-only: Quidax exposes no public order book, so the best bid/ask travel inside the ticker.
