Live market data for BitMEX, the original crypto perpetual-swap exchange, with no key. List the active instruments (perpetual swaps, futures and FX) with mark/last price, funding rate, open interest and 24h volume; pull a single-instrument ticker; read the live L2 order book split into bids and asks; stream recent public trades; and fetch bucketed OHLC candles. BitMEX uses XBT for Bitcoin — the flagship perpetual is XBTUSD. Ideal for derivatives dashboards, funding-rate monitors and charting across 130+ instruments.

Carbon API

Live on-chain data for Carbon (chain id carbon-1) — the Switcheo-built Cosmos-SDK Layer-1 for decentralised derivatives and spot trading, whose native token is SWTH — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated SWTH, commission rate and jailed flag. The supply endpoint returns the total SWTH supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. SWTH uses an 8-decimal base denomination which is converted to whole SWTH with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and DeFi ecosystem. Live keyless upstream. 5 endpoints.

Crypto Derivatives API

A cross-exchange aggregator of cryptocurrency perpetual-futures and derivatives markets — the funding rates, open interest and volume that drive leveraged crypto trading, pulled together across every listed derivatives exchange (Binance, Bybit, OKX, Hyperliquid, MEXC and dozens more). The perps endpoint ranks the largest perpetual markets by open interest with their price, funding rate, open interest and 24h volume. The funding endpoint compares the funding rate of one asset (e.g. BTC, ETH, SOL) across every exchange that lists it, with the average — so you can spot funding dislocations and basis trades at a glance. The exchanges endpoint ranks derivatives venues by open interest with their perpetual and futures pair counts. The overview endpoint aggregates total open interest, total 24h volume and the perpetual-pair count across the whole derivatives market. The meta endpoint documents the API. Live aggregated data, lightly cached; funding rates are percentages, open interest in USD per market and BTC for venue totals. Live. 5 endpoints. This aggregates derivatives across all exchanges; for a single exchange's raw order book use that exchange's API.

Deribit API

Live market data from Deribit — the leading crypto options and futures exchange. A keyless, no-account JSON wrapper over Deribit's public v2 API. Read the spot index price for any settlement currency (BTC, ETH, USDC, USDT), pull a full ticker for any instrument — last / mark / index price, best bid-ask, open interest and 8-hour funding for perpetuals, plus mark implied volatility and the greeks (delta, gamma, vega, theta, rho) for options — list the entire active instruments catalog by currency and kind (future, option, spot, combos) with strikes, expiries and contract sizes, and fetch per-currency order-book summaries across all live instruments. The raw exchange feed for derivatives desks, options dashboards, volatility models and trading bots — distinct from analytics products: this is Deribit's own ticker, instrument and book data, decoded into clean JSON.

WEEX Market Data API

Real-time perpetual-futures market data from the WEEX crypto exchange. List every live perpetual contract with its underlying index, quote and settle currency, contract value, tick size and size increment; pull 24-hour tickers for all 700+ contracts at once or one at a time (last price, best bid and ask, 24h high and low, traded and base volume, percentage change, mark price and index price); read full order-book depth with best bid, best ask and computed spread; and stream the most recent trades with price, size, notional value and side. Symbols use the WEEX cmt_ prefix (cmt_btcusdt) and accept either form (BTCUSDT or cmt_btcusdt). A short protective cache keeps responses fast while staying within a few seconds of the exchange. Distinct from our BitMEX, BloFin, Bitunix and Phemex exchange feeds: this surfaces the WEEX order book, ticker tape and contract registry specifically.
