```

Example prompt: Show me all Aave V3 positions on Base with a health factor below 1.1 that are close to liquidation — I want to see the collateral and debt breakdown and estimated profit for each one.

## When to prefer this

Use this endpoint when you need real-time identification of undercollateralized Aave V3 positions on Base for liquidation bot operations, risk monitoring dashboards, or DeFi analytics. Prefer this over generic on-chain queries when you want pre-computed health factors, collateral/debt breakdowns, and profit estimates in a single call.

## Known failure modes

- Invalid or unsupported protocol/chain combination returns error or empty result
- Threshold value out of expected range may return no positions or an error
- Demo mode may return synthetic data not reflecting real on-chain state
- Network latency or RPC issues on Base may cause timeouts
- Payment failure (x402) blocks access to endpoint
