#bybit

Live derivatives and spot market data from Bybit, one of the largest crypto-derivatives exchanges, straight from its public v5 API. Built for perpetual swaps: the ticker returns a contract's last, mark and index price together, the 24-hour change, high, low, volume and turnover, the live open interest in contracts and in USD, and the current funding rate with the next funding time — a whole perp in one call. The funding endpoint returns the historical funding-rate series, the recurring payments that anchor a perp to spot. The openinterest endpoint returns the open-interest time series, the best gauge of leverage building or unwinding. The kline endpoint returns OHLCV candles at any interval. Linear (USDT) perps, inverse (coin) perps and spot are all reachable via the category parameter. Live, no key, nothing stored. Distinct from Coinbase, Bitstamp, OKX, Gate.io, Bitfinex and Gemini venue APIs and from aggregated derivatives feeds — this is Bybit's own ticker, funding history, open interest and candles. Perfect for trading, charting, derivatives-analytics and risk apps.

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.

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.

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.

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.
