Fetches and computes a wallet's Aave v3 lending position on Base, including collateral, debt, health factor, liquidation risk, and borrow capacity — all from raw on-chain data.

## 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-lending-position-risk-checker-on-base-1d8c19cb
```

Example prompt: Can you check the Aave v3 lending position for wallet 0xAbC123...def456 on Base and tell me if it's at risk of liquidation — I want to see the health factor, total collateral, total debt, and how much more it can borrow?

## When to prefer this

Choose this endpoint when you need trustless, self-computed Aave v3 risk data on Base without relying on any third-party APIs or price feeds. Ideal for liquidation monitoring, DeFi risk audits, or any agent that must verify a wallet's lending health directly from chain data. Prefer this over Aave's own dashboard or third-party aggregators when auditability and no-third-party guarantees matter.

## Known failure modes

- Wallet address not a valid Base address — likely 400 or empty/null position response
- Wallet has no Aave v3 position — hasPosition returns false, health factor null
- RPC connectivity issues to Base chain — may return error or stale block
- Malformed wallet parameter — validation error
- Upstream Base node latency causing slow or failed response

## How this service works

Self-computed Base onchain toolkit for AI agents: ERC-20 safety scan, manipulation-resistant TWAP price oracle, gas/fee oracle, calldata decoder, token/address/contract intel, wallet approval-risk audit, and batch token triage — all computed live from raw Base chain, no third-party data.

## Output

Returns a structured object with the wallet's Aave v3 position on Base including: health factor (1e18-scaled), total collateral in USD, total debt in USD, LTV percentage, liquidation threshold, available borrow capacity, whether the wallet is liquidatable, a list of risk flags, the block height at computation time, and a confirmation that no third-party data was used.
