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 8, 2002, 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.
