## When to prefer this

Choose this endpoint when you need real-time, bot-ready Aave V3 near-liquidation signals specifically on Base and Arbitrum, especially for liquidation bots, DeFi risk dashboards, or automated monitoring agents that need fresh on-chain health factor data without running their own RPC scanner infrastructure.

## Known failure modes

- Payment not provided or invalid x402 payment header — returns 402 Payment Required
- Scanner data stale or unavailable — may return empty or partial results
- Chain-specific scanner outage — Base or Arbitrum data may be missing
- Rate limiting — too many requests in short window
- Invalid query parameters — returns 400 Bad Request
