Crypto Derivatives API

4,152 Subscribers
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.

Superposition API
Live EVM on-chain data for Superposition (chain id 55244) — an Arbitrum-Orbit DeFi Layer-3 with ETH gas and on-chain yield-bearing Super Assets — served directly from the public Superposition JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and DeFi analytics across the Superposition and Arbitrum-Orbit ecosystem. Live keyless upstream. 5 endpoints.
