US Company Financials & Fundamentals API

healthy 3,661 Subscribers

Live fundamental financials for US public companies straight from the SEC's official XBRL data — no key, nothing stored. The "what does the balance sheet and income statement say" view of a company: the actual reported revenue, earnings, assets and equity pulled from its SEC filings, distinct from the quote, analyst, insider and SEC-filings (EDGAR) APIs in the catalogue. The financials endpoint returns the latest annual key figures: revenue, gross profit, operating income, net income, total assets, total liabilities, shareholders' equity, cash, diluted EPS and the computed net margin. The concept endpoint returns the multi-year time series for a single metric — revenue history, net-income history and more — so you can chart how a company has grown. The company endpoint resolves a ticker to its SEC company (CIK and legal name). Build stock-screeners, valuation models, fundamentals dashboards and research tools on top of authoritative SEC data. Look up any US public company by its ticker; figures are the latest annual (10-K) values reported to the SEC in USD.

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.
