Stock Short Interest API

3,881 Subscribers
Live short-interest data for US stocks from Nasdaq — no key, nothing stored. The "how heavily is it shorted, and is a squeeze building" view of a stock: the number of shares sold short, the average daily volume and the resulting days-to-cover, reported each settlement period, distinct from the quote, movers, insider and analyst APIs in the catalogue. The current endpoint returns the latest short-interest reading together with the change from the prior period — a rising or falling short position with the share delta and percent change. The history endpoint returns the full settlement-by-settlement timeline so you can see how the short position has trended over the year. Days-to-cover — short interest divided by average daily volume — is the headline squeeze metric: the higher it is, the longer shorts would need to buy back their position. Build short-squeeze scanners, bearish-positioning dashboards, risk overlays and contrarian-signal bots on top of real Nasdaq short-interest data. Look up any US stock by its ticker; share counts are returned as clean numbers. Note that short interest is reported about twice a month and a few non-Nasdaq listings may not be covered.

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.
