Example prompt: Can you scan Aave V3 on Base for positions with a health factor below 1.1 and show me which ones are closest to liquidation along with the estimated profit I'd earn from liquidating each one?

## When to prefer this

Use this endpoint when you need to identify at-risk Aave V3 lending positions specifically on the Base network and want collateral/debt detail plus liquidation profit estimates in one call. Prefer it over generic DeFi dashboards when you need liquidation-specific analytics with configurable health factor thresholds.

## Known failure modes

- No positions found below threshold — returns empty list
- Invalid protocol or chain parameter — returns error
- Demo mode returns synthetic/mock data rather than live on-chain data
- RPC or indexer unavailable — may return stale or partial data
- Payment not processed — 402 response if x402 payment header missing
