## 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 xx402-base-wallet-watchlist-risk-digest-1eae6483
```

Example prompt: Can you run a risk digest on these two Base wallets — 0xAbC123...def and 0x789XyZ...fed — checking their USDC activity over the last 2000 blocks, looking at up to 5 counterparties each, and tell me if either one lands on the watchlist or avoid queue?

## When to prefer this

Choose this endpoint when you need a rapid, structured risk classification of one or more Base/EVM wallet addresses relative to a specific ERC20 token — especially for autonomous agent payment flows, DeFi onboarding checks, or compliance screening where a human-readable risk digest with watchlist decisions and counterparty exposure is more useful than raw chain data.

## Known failure modes

- Invalid or malformed wallet address returns validation error
- Token address not matching ERC20 pattern returns schema error
- Limit parameters out of range (e.g. limit > 5 or detail_limit > 10) rejected
- Block window outside 100–5000 range returns error
- No on-chain data found for address in the specified window returns empty result
- Payment not completed (x402 protocol failure) blocks response
- Rate limiting or provider downtime may return 402 or 5xx
