Crypto Basis API

healthy 4,769 Subscribers

Live crypto spot-versus-perpetual basis and premium as an API, served from the Bybit v5 feed. The basis is the gap between a coin's perpetual-futures price and its spot price: when the perp trades above spot the market is in contango (leveraged longs are paying up), when below it is in backwardation. For any coin this returns the spot price, the perp last, mark and index price, the basis in absolute and percentage terms, the mark-to-index premium, the market structure, and the funding rate — per-8-hour and annualised — that arbitrages the basis away. Get a coin's basis, or scan the majors ranked by basis. The cash-and-carry and funding-arbitrage signal layer for trading and dashboard apps. Live, no key, no cache. Distinct from funding-rate, open-interest and price APIs — this is the spot-perp basis.

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.

Ticker-only: Quidax exposes no public order book, so the best bid/ask travel inside the ticker.
