Daily end-of-day stock prices (open/high/low, close, split- & dividend-adjusted adj_close, volume) for US exchange-listed companies. Sourced from a market-data feed, not SEC filings.
Markets are open only on business days, so rows exist ONLY for trading days — the data IS the trading calendar:
- Price ON OR AFTER a date (e.g. an announcement landing on a weekend): pass start_date=<date>; the FIRST row is that date or the next open day.
- Price ON OR BEFORE a date: pass end_date=<date>; the LAST row is that date or the prior open day.
- A single specific date: pass start_date=<date> (omit end_date) — returns a short forward window whose first row is your on/after price.
Use Cases:
- "AAPL close on 2025-07-28" -> get_stock_price("AAPL", start_date="2025-07-28") (first row = that day or next open day)
- "DKNG total return 2025-01-02 → 2026-02-27" -> TWO calls: get_stock_price("DKNG", start_date="2025-01-02") and get_stock_price("DKNG", end_date="2026-02-27"); take each first/last close and compute the return (cheaper than one 14-month window)
- "SUI 1/14/30 calendar days after an 8-K date" -> get_stock_price("SUI", start_date="<announce>", end_date="<announce + ~32d>"), then pick the first row on/after announce, +1, +14, +30
- "Latest price" -> get_stock_price("AAPL")
When the window spans ≥2 trading days, the response also reports the first/last close and the period return on BOTH close (literal point-to-point) and adj_close (split/dividend-adjusted — the true economic return; the two diverge across a split or dividend).
Each response also includes the latest REPORTED period-end shares outstanding on/before your end date (period-end balance-sheet count; dei cover where absent) plus the implied market cap at the latest close — use these for market-cap / EV / P/B math instead of deriving share counts from NI/EPS (that yields weighted-average shares, a different basis).
Coverage: ~8,400 US common-equity tickers, end-of-day only (no intraday/real-time, no options/FX). Recent history is dense; deep pre-2014 history may be sparse. For period-end valuation multiples (P/E, EV/EBITDA, P/B) use get_metric_history; to assemble a CUSTOM multiple (e.g. lease-adjusted EV) combine this price with get_metric_history("ticker","oper_lease_liabs" / "ttl_debt" / "cash_st_invs" / "ttl_equity" / "shares_basic").
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| ticker | string | yes | Company ticker symbol (e.g., 'AAPL'). US exchange-listed (NYSE/Nasdaq/AMEX), 1–5 letters. |
| start_date | string | no | Window start (YYYY-MM-DD). Markets trade only on business days — if this date is a weekend/holiday the FIRST returned row is the next OPEN day (the price ON OR AFTER this date). Omit end_date to fetch just the price on/after this date. |
| end_date | string | no | Window end (YYYY-MM-DD). The LAST returned row on/before this date is the price ON OR BEFORE it. Omit start_date to fetch just the price on/before this date. |
| limit | integer | no | Max rows (newest first if the window exceeds it). Default 30. For a point-to-point return over a long span, make TWO narrow-window calls (one per date) rather than one wide window — cheaper, and avoids the cap dropping your start date. |
