## When to prefer this

Choose this endpoint when you need historical risk signal data from the Kronos quantitative engine — particularly for backtesting forecast accuracy, auditing past risk assessments, or understanding how signals evolved over time for crypto, commodities, or pre-market equities. Prefer this over real-time forecast endpoints when retrospective analysis is the goal.

## Known failure modes

- Payment required (402) if USDC micropayment not attached
- Invalid or unsupported asset symbol returns 400 or empty result
- No historical data available for very new or illiquid assets
- Rate limiting if too many calls made in rapid succession
- Stale data if upstream market feed is delayed
