Intraday Stock Candles API

healthy 4,445 Subscribers

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.

Chart Convert API

Live conversion of OHLC candles into the alternative chart types traders use to filter noise — computed on demand, no key, nothing cached. Convert candles to Heikin-Ashi (which smooths price action and clarifies trend); build Renko bricks from a price series and a brick size (stripping out time and small moves); and produce a Three Line Break chart (which only prints a new line on a confirmed move). Each carries the latest trend direction. Works for any market — forex, stocks, crypto or commodities. A chart-transformation engine, distinct from pattern-detection and indicator tools: it turns ordinary candles into the trend-clarifying chart types a discretionary trader reads.

Crypto History API

Live historical price data and analytics for any crypto coin, from the public CoinGecko feed. Get open/high/low/close candles over a date range; the price, market cap and volume time series; the move over a period with its high and low; and a coin's multi-period performance with all-time-high and all-time-low. Works for thousands of coins in any quote currency. A crypto history-and-analytics layer — distinct from spot-price and whole-market feeds: it turns the price archive into the candles, time series and moves a trader studies. Live, with a short upstream cache.

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.

Earnings Surprise (Beat/Miss) API

Live earnings beat/miss track record for US stocks from Nasdaq — no key, nothing stored. The "does it beat the street" view of a stock: how its actual reported EPS has compared to the analyst consensus over the recent quarters, distinct from the earnings-calendar (upcoming dates), analyst (forward estimates) and financials APIs in the catalogue. The surprises endpoint returns the recent quarters with the actual EPS, the consensus forecast, the dollar and percent surprise, and whether the quarter was a beat, a miss or in line. The scorecard endpoint computes the track record — how many of the recent quarters beat, the beat rate, the average surprise, the latest result and the current beat/miss streak — so you can gauge how reliably a company tops expectations. Build earnings-quality screeners, beat-streak scanners, post-earnings-drift signals and event-driven trading tools on top of real Nasdaq earnings-surprise data. The surprise is the actual reported EPS versus the analyst consensus for the quarter; a positive percent surprise is a beat. Look up any US stock by its ticker.
