#perpetuals

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.

The perpetual-futures funding rate for a coin side by side across the major exchanges, and the spread between them — computed live from each venue's public API, no key, nothing stored. A perpetual swap charges or pays funding every few hours to keep its price tethered to spot; when the same coin's funding differs across exchanges, a trader can be long the perp where funding is most negative (and gets paid) and short where it is most positive, harvesting the spread market-neutral. The funding endpoint returns, for a coin, the current funding rate on Binance, Bybit, OKX and Gate.io — per interval and annualised — the venue paying the most, the one charging the most, and the cross-exchange spread (the arbitrage edge). The screener endpoint scans a basket and ranks the coins by the size of that spread, surfacing the biggest funding-arbitrage opportunities. This is the cross-exchange funding-rate / basis-arbitrage cut for crypto — distinct from the single-exchange funding-rates feed (one venue), the spot-versus-perpetual basis and the price APIs in the catalogue. Funding is per interval (most venues settle every 8 hours); annualisation assumes three settlements a day, and intervals can differ by venue, so verify before trading. Coins are bases (BTC, ETH).

Live ranking and directory of crypto derivatives venues — the platforms that run perpetual and futures markets — served from the public CoinGecko feed with no key and nothing cached. This is a venue-level view of the derivatives market, distinct from spot-exchange directories, per-contract open-interest feeds and single-exchange tickers: it ranks the derivatives platforms themselves. The exchanges endpoint returns the venues ranked by open interest (or by 24-hour volume), each with its open interest in BTC, 24-hour derivatives volume in BTC, the number of perpetual and futures pairs it lists, its country and the year it was established — so one call tells you who the biggest derivatives venues are and how concentrated open interest is. The exchange endpoint returns a single venue's full profile by id. The list endpoint returns every derivatives-exchange id and name for lookup and autocomplete. Everything is read live from CoinGecko on each request, nothing stored beyond a short protective cache. Ideal for derivatives dashboards, open-interest and market-structure analytics, venue comparison and trading tools. Live, no key. 3 endpoints. For per-contract funding and open-interest history use a derivatives or open-interest API.

Live market data from Bitget, a top-tier centralised crypto exchange. The ticker endpoint returns a spot or USDT-perpetual symbol's last price, bid/ask, 24h high/low, volume and change. The tickers endpoint returns the top symbols by 24h volume for the spot or futures market. The funding endpoint returns a perpetual contract's current funding rate, funding interval, next funding time and open interest — the derivatives data traders watch. Read live from Bitget, nothing stored. This is Bitget's own spot and USDT-perpetual ticker, funding-rate and open-interest layer — a distinct centralised-exchange venue, separate from other exchange feeds and from DEX, lending and oracle APIs.

Live oracle prices from GMX, the leading decentralised perpetual-swap exchange on Arbitrum and Avalanche. Unlike order-book DEXs, GMX executes trades against its GLP/GM liquidity pools at prices set by a keeper-signed oracle that quotes a MIN and a MAX price per token — the execution band traders open and close positions against. The prices endpoint returns every supported token's min/max/mid oracle price and the execution spread; the price endpoint returns a single token by symbol; the tokens endpoint returns the supported-token registry (contract address, decimals, synthetic flag); the spread endpoint ranks tokens by their oracle execution spread (the on-chain cost band of trading that token on GMX). Every endpoint accepts a chain parameter (arbitrum default, or avalanche). Read live from GMX's public oracle, nothing stored. This is GMX's own pool-DEX oracle min/max-price and execution-spread layer — distinct from centralised-exchange tickers, aggregate price feeds and order-book DEX feeds such as dYdX and Hyperliquid.

Live on-chain exchange data from the Injective network (INJ), a layer-1 blockchain with a fully on-chain central-limit order book for spot and derivative trading: the on-chain spot markets with ticker, status, fees and tokens; the perpetual and futures markets with their live mark price, oracle, margin ratios and fees; a spot market's live on-chain order book (best bid/ask, mid, spread and depth, decoded to human prices); and single-market details.

Live cross-exchange perpetual-futures market data — no key, nothing cached. Where single-exchange APIs show one venue, this compares the whole derivatives market across every exchange at once. The contract endpoint takes a symbol (BTCUSDT, ETHUSD) and returns that contract on every exchange that lists it — the mark price, the funding rate, the basis, the open interest and the 24-hour volume on Binance, Bybit, OKX, MEXC, Hyperliquid and the rest side by side, so you can instantly see where funding is richest and where the open interest sits (BTCUSDT trades on dozens of venues with billions in open interest each). The exchanges endpoint is the derivatives-exchange league table, ranked by open interest in BTC, with each venue's 24-hour volume and number of perpetual and futures pairs. The top endpoint surfaces the largest contracts market-wide by open interest or by volume. This is the cross-exchange derivatives layer for any trading, funding-arbitrage, risk or analytics app. Live from CoinGecko, nothing stored. Distinct from single-exchange funding and open-interest APIs — this is the whole perpetual-futures market across exchanges. 4 endpoints.

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.

api.oanor.com/cryptobasis-api

Live open-interest history and trend for crypto perpetual futures, served from the Bybit v5 feed. Open interest is the total value of outstanding contracts — its trend, rising or falling alongside price, is the signal traders use to confirm a move or spot a squeeze. For any USDT perpetual this returns the latest open interest in contracts and in USD, how it has changed over your chosen window, the rising / falling / flat trend, and the full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets. Look a contract up by symbol (BTCUSDT) or base coin (BTC), pull its open-interest history, or list every tradable perpetual. Live data, no cache. Distinct from a funding-rate API (which carries the rate snapshot) and from price / ticker APIs — this is the open-interest time-series and trend layer.

api.oanor.com/openinterest-api

Live crypto long/short trader-positioning sentiment as an API, streamed from the Bybit v5 public account-ratio feed. For any USDT perpetual futures contract it returns the share of accounts positioned long versus short (buy/sell ratio) and the derived long/short ratio — either the latest reading or a full time-series across 5m, 15m, 30m, 1h, 4h and 1d buckets. The crowd-positioning signal traders use to spot one-sided, over-leveraged markets. Look up by symbol or base coin, pull history, or list tradable symbols. Live, no key. Distinct from funding-rate, price and open-interest APIs — this is the account long/short sentiment.

api.oanor.com/longshortratio-api

Live crypto perpetual funding rates and derivatives data as an API, streamed from the Bybit v5 public market feed. For every USDT perpetual futures contract: its symbol, last / mark / index price, the current funding rate (per interval, plus percentage and annualised), the next funding time, open interest, 24-hour volume and turnover, and 24-hour price change. Look a contract up by symbol or base coin, rank contracts by funding, open interest, turnover or price move — a ready-made signal for crowded longs and shorts — search, or list them all. Built for trading, quant, dashboard and signal apps. Distinct from spot-price and on-chain data.
