Stock Short Interest API

healthy 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.

Intraday Stock Candles API

Live intraday and historical OHLCV candles for stocks, indices, ETFs, crypto and FX, served from Yahoo Finance's public chart feed. The candles endpoint returns regular-session bars — open, high, low, close and volume — at a chosen interval (1m, 2m, 5m, 15m, 30m, 60m, 90m, 1h, 1d, 1wk, 1mo) over a range, each bar timestamped. The extended endpoint returns the pre-market and after-hours (extended-hours) bars, each labelled with its session. The latest endpoint returns an intraday snapshot — current price, day change and percent, the day open/high/low and volume, the 52-week range and the most recent bar. Symbols follow Yahoo conventions: US tickers (AAPL, MSFT), indices (^GSPC, ^IXIC), crypto (BTC-USD) and FX (EURUSD=X). This is the intraday candlestick / OHLCV view — per-minute to hourly bars plus extended hours — distinct from the daily price-history, the live-quote and the FX/rate APIs in the catalogue. Live, no key on the upstream, nothing stored.

Stock Options Chain API

Live (15-minute delayed) US equity and index options chains, served from CBOE's public delayed-quotes feed. For any optionable ticker the summary endpoint returns the underlying quote — current price, day change, open/high/low/close, volume, bid/ask and the 30-day implied volatility (IV30) with its change. The expirations endpoint lists every available expiration date with its call and put contract counts. The chain endpoint returns the option contracts themselves: for each strike and expiry it gives the call/put bid, ask, last, implied volatility, open interest, volume and the full greeks — delta, gamma, theta and vega — and can be filtered by expiration date and by call or put. US index options are addressed with an underscore prefix (_SPX, _VIX). This is the single-name equity and index options surface — strikes, expiries, IV and greeks — distinct from the options-pricing calculators, the crypto-options and the FX/rate APIs in the catalogue. Live, no key on the upstream, nothing stored.

Coincheck Exchange API

Live market data from Coincheck, one of Japan's largest retail crypto exchanges (Monex Group), straight from its public REST API. This is the single-venue Japanese-Yen (JPY) view. The ticker endpoint returns the live BTC/JPY summary — last price, bid, ask, 24h high/low and 24h volume. The orderbook endpoint returns the live BTC/JPY bid/ask depth with per-level price and size, plus the best bid/ask and the resulting spread. The trades endpoint returns the most recent executed trades for any listed pair, with price, amount, side and time. The rate endpoint returns the current Japanese-Yen price of any listed coin (BTC, ETH, XRP, ETC …). Together they answer "what does crypto cost in Japanese Yen on Coincheck right now, how deep is the BTC book, and what just traded" — a single-venue JPY-denominated exchange view, distinct from the aggregated cross-exchange market, whole-market overview and other regional exchange APIs in the catalogue. Live, no key on the upstream, nothing stored.

BitoPro Exchange API

Live market data from BitoPro, Taiwan's largest regulated retail crypto exchange, straight from its public v3 REST API. This is the single-venue New-Taiwan-Dollar (TWD) order-flow view. The ticker endpoint returns the last price, 24h change, 24h high/low and 24h base volume for any listed pair (BTC_TWD, ETH_TWD, USDT_TWD …), or every pair at once ranked by volume. The orderbook endpoint returns the live aggregated bid/ask depth with per-level price, size and order count, plus the resulting best bid/ask and spread. The trades endpoint returns the most recent executed trades with price, amount, side and time. The pairs endpoint lists every tradable market with its base/quote, precision and order limits, and which markets are in maintenance. Together they answer "what does BTC cost in New Taiwan Dollars on BitoPro right now, how deep is the book, and what just traded" — a single-venue TWD-denominated exchange view, distinct from the aggregated cross-exchange market, whole-market overview and other regional exchange APIs in the catalogue. Live, no key on the upstream, nothing stored.
