Crypto Options API
Live crypto options-market data as an API, streamed from the Deribit public exchange. For BTC, ETH, SOL and XRP: the full option chain with each contract's mark price, mark implied volatility, open interest, 24-hour volume and underlying price; the nearest at-the-money call and put for a one-call read on how the market prices risk; the spot index price; the historical realised-volatility series with stats; and a market-wide summary of open interest, volume and expiries. Built for options, volatility, quant and trading apps. Distinct from spot-price, funding and on-chain APIs — this is the live options 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.

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.
