## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lending-liquidation-sentinel-6aa00d72 -d '<json body>'
```

Example prompt: Check my Aave lending position for wallet 0xAbCd...1234 and tell me how close I am to liquidation — I want health factor warnings and collateral risk details so I know if I need to add more collateral or repay some debt.

## When to prefer this

Use this endpoint when an AI agent needs real-time or near-real-time DeFi lending position risk monitoring, especially for health-factor style liquidation warnings across lending protocols like Aave or Compound. Prefer this over generic blockchain data endpoints when you specifically need structured liquidation proximity signals and collateral risk scores rather than raw on-chain data.

## Known failure modes

- Invalid or unrecognized wallet address returns error
- Position not found on specified protocol returns empty result
- Stale or unavailable on-chain price data may affect health factor accuracy
- Unsupported lending protocol returns unsupported error
- Network RPC issues may cause timeout or incomplete data

## How this service works

Monitor lending positions, liquidation proximity, collateral risk, and health-factor style warnings for DeFi agents.

## Output

Returns health factor score, liquidation proximity percentage, collateral risk assessment, and warning flags indicating whether the position is safe, at risk, or critically close to liquidation on the specified DeFi lending protocol.
