Use this endpoint when you need historical candlestick/OHLCV time series data for stocks, forex pairs, or crypto assets across a wide range of intervals (1-minute through monthly). Prefer this over snapshot/quote endpoints when you need multiple historical data points for charting, backtesting, or technical indicator computation.

- Unsupported interval string causes a bad request error
