Custom Stock Bars

Choose this endpoint when you need flexible OHLCV bar data at any custom resolution (e.g. 5-minute, 2-hour, 3-day) for a single stock ticker over a specific date range. Prefer this over the Daily Ticker Summary endpoint when you need intraday or multi-period aggregates rather than a single day's open/close, and over technical indicator endpoints (SMA, EMA) when you need raw price data rather than derived signals.

• Invalid ticker symbol returns empty results or error
• Date range with no trading data (e.g. holidays, weekends with daily bars) may return empty results
• Multiplier must be a positive integer string; invalid format returns a validation error
• Timespan enum must be one of: minute, hour, day, week, month, quarter, year — otherwise 400 error
• Limit exceeds 50000 — request will fail or be capped
• From date after To date returns an error or empty results
• Network or payment failure (x402 protocol issue) returns 402 Payment Required
