About the A1PH34 data

Daily bars. 1,638 sessions from Mar 3, 2020 to Sep 28, 2026, one row per B3 trading day with open, high, low, close and volume. Prices are adjusted for splits and cash dividends so the series is comparable across its whole length; the API also serves the raw, split only and dividend only views.

Minute bars. Not stored for this listing yet. Minute history is captured forward from the day collection begins for a symbol and is never backfilled.

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 Mar 3, 2020, 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.
