About the ECOM3 data

Minute bars. Stored from Sep 17, 2026 forward, most recent session Sep 28, 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 B3 trading days; minute timestamps are UTC. Prices are in BRL. Volume is shares traded on the session.
Get the data. 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 Jul 28, 2021, 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.
