Minute bars. Stored from Sep 16, 2026 forward, most recent session Nov 11, 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.

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 Aug 27, 2025, 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.
