## When to prefer this

Choose this endpoint when you need micropayment-accessible liquidation cluster data for crypto markets at very low cost ($0.01 per call). It is suitable for AI agents with x402 USDC payment capability that need quantitative liquidation level data for trading decisions, risk management, or algorithmic strategy inputs. Prefer alternatives if you need guaranteed SLAs, rich documented schemas, or institutional-grade data reliability.

## Known failure modes

- Payment not included or rejected — 402 response requiring valid USDC x402 payment header
- Stale or cached data if market moves rapidly between calls
- Undocumented response schema may require parsing trial-and-error
- Service unavailability from a small independent provider
- Rate limiting if too many calls are made without payment
- Empty or sparse data during low-volatility or off-hours market conditions
