Market open brief
Full pre-trade snapshot for one ticker before the bell: the live quote, the pre-market quote, the options surface, dividend posture, and today's market-wide earnings calendar — one payment.
When to use this pack
An agent positioning ahead of the open needs everything that moves a pre-trade decision: where the stock closed, where pre-market has taken it, what the options chain implies, whether a dividend is imminent, and which earnings prints hit the tape today.
Tools in this pack
- Stock quote $0.003 GET /api/stock-quote Live stock/index/FX/crypto quote: last price, day range, 52-week range, previous close, currency, exchange, and a relative change vs. previous close, as clean JSON. Backed by Yahoo Finance's public chart endpoint — keyless, no rate limits in practice. Symbols: equities (AAPL), indices (^GSPC), FX (EURUSD=X), crypto (BTC-USD).
- Pre/post-market quote $0.003 GET /api/premarket-quote Extended-hours quote for a US-listed ticker: latest traded price including pre-market and after-hours sessions, which session it printed in (pre / regular / post / closed), change vs. the last regular-session price, and today's session windows. Backed by Yahoo Finance's chart endpoint with includePrePost.
- Options chain $0.005 GET /api/options-chain Option chain for a US-listed ticker: all listed expiration dates, the strike ladder, and per-contract bid/ask/last/volume/open-interest/implied-volatility for calls and puts at one expiry (nearest by default, or pass `expiration` as YYYY-MM-DD). Backed by Yahoo Finance's options endpoint with the session-crumb handshake handled server-side.
- Stock dividends & splits $0.003 GET /api/stock-dividends Dividend and stock-split history for a ticker: every cash dividend (ex-date + amount) and split (date + ratio) over a configurable range (default 5y, up to max). Empty arrays for non-payers — a valid answer, not an error. Backed by Yahoo Finance's chart endpoint with events=div,split.
- Earnings calendar $0.015 GET /api/earnings-calendar Earnings calendar for a given date — every company reporting that day with EPS estimate, EPS actual (if reported), and reporting time slot. Optional `symbol` filter narrows to one ticker. Defaults to today (UTC). Backed by Nasdaq's public calendar API.
Workflow
- Get the live quote from stock-quote — last price, day range, 52-week range, volume.
- Pull the pre-market quote from premarket-quote — where the stock is trading before the bell and the gap versus the prior close.
- Fetch the options chain from options-chain — strikes, bids/asks, and implied volatility for the nearest expiry.
- Check dividend posture with stock-dividends — recent payouts and whether an ex-dividend date is close.
- Pull today's market-wide earnings calendar from earnings-calendar — every company reporting today, so no print ambushes the open.
