Market Calendar API

healthy 3,215 Subscribers

Live corporate-events calendar for US-listed stocks — the dates that move markets — served straight from Nasdaq's public calendar feed. For any trading day it answers the three questions a trader's calendar needs. The earnings endpoint lists every company reporting on a date with the session (pre-market or after-hours), the consensus EPS forecast, the number of analyst estimates, market cap and the year-ago actual EPS — so you can see, for example, Oracle reporting after the close with a $1.58 consensus against $1.35 a year earlier. The dividends endpoint gives the dividend calendar: the ex-dividend, record and payment dates, the per-share rate and the indicated annual dividend. The splits endpoint gives the stock-split calendar with the split ratio and execution date. This is the forward event-calendar layer every trading, portfolio, screener, earnings-tracker and finance app needs — read live from Nasdaq, nothing cached or stored. Pass any date as YYYY-MM-DD, or omit it for today. Distinct from price, quote and fundamentals APIs — this is the forward calendar of corporate events: who reports, who pays, who splits, and when. 4 endpoints.

Earnings Surprise (Beat/Miss) API — oanor API marketplace

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.

 US Company Financials & Fundamentals API — oanor API marketplace

US Company Financials & Fundamentals API

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.

 Earnings & Stock Splits Calendar API — oanor API marketplace

Earnings & Stock Splits Calendar API

Live US corporate-events calendar from Nasdaq — no key, nothing stored. The earnings and stock-splits calendar: which companies report earnings on a given day and which stocks are about to split, distinct from the economic-calendar, IPO-calendar and dividend APIs in the catalogue. The earnings endpoint returns every company reporting on a date — ticker, name, the consensus EPS forecast, the reporting time (before market open or after market close), market cap, the number of analyst estimates, the fiscal quarter ending and the prior-year EPS and report date — ranked by market cap. The splits endpoint returns the upcoming stock splits: ticker, name, the split ratio and the execution date. Build earnings-season dashboards, event-driven trading bots, investor-relations trackers and "who reports today" widgets on top of real Nasdaq calendar data. The earnings endpoint defaults to today (US Eastern) and accepts any date; EPS and market cap come back as clean numbers and reporting time is normalised to pre-market, after-hours or unspecified.
