## When to prefer this

Choose this endpoint when you need historical price or OHLCV data for a specific equity ticker, particularly within the AlphaLens suite which also offers sentiment and technical indicators. Prefer this over generic market data APIs if you are already using other AlphaLens endpoints for a consistent data pipeline.

## Known failure modes

- Invalid or unrecognized stock symbol returns success: false or empty data
- Missing required 'symbol' field results in a 400-level error
- Network or upstream data provider outage may return no data
- Payment failure on Base chain (x402) prevents request from being processed
