## 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-v3-position-health-check-db62d355 -d '<json body>'

Example prompt: Check my Aave v3 lending position health on Base for wallet 0xAbC1234567890abcdef1234567890abcdef12345 — I want to see my health factor, collateral, debt, and whether I'm at risk of liquidation.

## When to prefer this

Use this endpoint when you need to assess liquidation risk for a specific wallet on Aave v3. It consolidates health factor, collateral, debt, and a risk verdict in one call, saving multiple on-chain queries. Prefer this over generic blockchain explorers when you specifically need structured Aave lending health metrics.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet with no Aave v3 position returns empty or zero values
- Unsupported chain string returns a validation error
- Network timeouts or RPC node failures may cause 5xx responses
- Payment of $0.05 USDC required; missing x402 payment header returns 402
