Minute bars. Stored from Jul 13, 2026 forward, most recent session Oct 23, 2026. Minute history is captured from the day collection began and is never backfilled, so this start date is exact. Five minute, fifteen minute and hourly bars are derived from these minutes.
Time and currency. Session dates are NYSE trading days; minute timestamps are UTC. Prices are in USD. Volume is shares traded on the session.

The REST endpoint returns the daily series as JSON with pagination; a free key serves the last year, Quant and above the full history back to Jan 29, 2026, and minute bars come with the paid windows. It takes timeframe (1Min, 5Min, 15Min, 1Hour, 1Day), adjustment, start and end. See the bars endpoint and authentication, and pricing for the plan windows.
