US Stock Market Movers API

healthy 3,058 Subscribers

Live US market movers from Nasdaq — no key, nothing stored. The "what's moving today" view of the US stock market: the day's biggest gainers, biggest losers and most-active names across stocks, ETFs and mutual funds, distinct from the index-constituent, single-quote and crypto-movers APIs in the catalogue. The gainers endpoint returns the top advancing names with their last price, price change and percent change. The losers endpoint returns the top declining names. The active endpoint returns the most-active names by share volume — or by dollar volume — with their last price and price change. Each endpoint takes an asset class: stocks (default), etf or funds. Build market-dashboard tickers, daily-mover newsletters, momentum scanners and trading-idea bots on top of real Nasdaq market-movers data. Data updates through the US trading day and is static outside market hours; prices and percentages are returned as clean numbers.

Put/Call Ratio & Options Sentiment API

Live (15-minute delayed) options put/call sentiment analytics for US stocks and indices, computed from CBOE's public delayed-quotes feed. The ratio endpoint aggregates the entire option chain into the headline sentiment gauges — the put/call ratio by volume and by open interest, the total put and call volume and open interest, the contract counts, and the underlying price with its 30-day implied volatility (IV30) — plus a plain-language sentiment lean. The expiries endpoint breaks the put/call ratio down by expiration date, giving the term structure of sentiment. The strikes endpoint maps call-versus-put volume and open interest across strikes for an expiration, showing where positioning sits. This is the computed options-sentiment and positioning view — ratios and skew, not a contract dump — distinct from the raw options-chain, the volatility-index and the options-pricing calculators in the catalogue. US index options use an underscore-prefixed symbol (_SPX, _VIX); a ratio above 1 means more puts than calls (defensive/bearish lean). Live, no key on the upstream, nothing stored.

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.
