## 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 aave-health-factor-68e5b689
```

Example prompt: What's the current Aave V3 health factor and liquidation risk for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 on Ethereum — how much collateral do they have, what's their debt, and how far can the collateral fall before liquidation?

## When to prefer this

Use this endpoint when you need real-time Aave V3 position data (health factor, collateral, debt, LTV) for a specific wallet across major EVM chains. Ideal for liquidation monitoring agents, DeFi risk dashboards, or pre-borrow safety checks. Prefer this over on-chain RPC calls directly when you want a single structured response without writing Solidity ABI queries.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Unsupported chain name returns an error — only ethereum, base, arbitrum, optimism, polygon are valid
- Wallet with no Aave V3 position returns zeroed-out values or a 404
- RPC node outage on the target chain may cause a 503 or timeout
- Missing required 'address' query parameter returns a validation error
- x402 payment failure or insufficient USDC balance results in 402 Payment Required

## How this service works

Aave V3 position of any wallet: collateral, debt and remaining borrowing power in USD, LTV, liquidation threshold, health factor and how far collateral can fall before liquidation. Use for liquidation alerts.

## Output

Returns a structured JSON object with the wallet's total collateral in USD, total debt in USD, available borrowing power in USD, current loan-to-value ratio, liquidation threshold, health factor (a ratio where values below 1.0 trigger liquidation), and the percentage drop in collateral value that would cause liquidation.
