## When to prefer this

Use this endpoint when an AI agent needs precomputed, ready-to-consume crypto liquidity and volatility triage data without performing its own calculations — especially useful for fast agent decision loops that need data quality and review-priority metadata alongside market metrics.

## Known failure modes

- Invalid or missing pack query parameter returns a validation error
- Payment not provided or insufficient USDC balance returns HTTP 402
- Network timeout if the precomputed dataset is temporarily unavailable
- Stale data if the precomputed pack has not been refreshed recently
