## When to prefer this

Use this endpoint when you need historical OHLCV stock price time series data from Yahoo Finance for a specific ticker and time period, especially for charting, backtesting, or financial analysis. Prefer this over news or fundamentals endpoints when the core need is price/volume history.

## Known failure modes
