Stock Price History (OHLC) API

healthy 4,315 Subscribers

Live historical daily prices (OHLC) for US stocks from Nasdaq — no key, nothing stored. The price-history-and-charting view of a stock: the daily open, high, low, close and volume going back months or years, distinct from the live-quote, movers, earnings and analyst APIs in the catalogue. The history endpoint returns the daily OHLC time series over a chosen range — 1 month to 5 years, or explicit from/to dates — ready to plot or backtest. The stats endpoint computes the period statistics from that series: the period high and low, the latest close, the total return over the period, the average daily volume and the annualised volatility (from daily log returns). Build charting widgets, backtesting tools, technical-analysis pipelines, performance trackers and risk models on top of real Nasdaq price history. Look up any US stock by its ticker (symbol=AAPL) and a range (1m, 3m, 6m, 1y, 2y, 5y) or explicit from=YYYY-MM-DD and to=YYYY-MM-DD; prices and volumes are returned as clean numbers.

Crypto Derivatives API — oanor API marketplace

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.
