## 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 asterpay-wallet-reputation-score-99118288
```

Example prompt: Can you check the reputation score and risk level for the wallet address 0xabc123...def456 before I send funds to it?

## When to prefer this

Use this endpoint when you need a fast, scored risk assessment of a specific wallet address before executing a transaction, onboarding a counterparty, or screening an incoming payment. Prefer this over full KYA deep-analysis endpoints when you need a lightweight score quickly and don't need the full 7-component breakdown.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unknown or brand-new wallet with no on-chain history may return minimal data
- Network timeout if on-chain data provider is slow
- Payment failure (402) if USDC balance is insufficient
