## 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 wallet-risk-signals-brief-sanctions-check-multi-chain-scan-1f152def -d '<json body>'
```

Example prompt: Can you run a full risk check on the Ethereum wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to know if it's on any sanctions lists and what its activity looks like across chains?

## When to prefer this

Choose this endpoint when you need a fast, all-in-one wallet risk assessment without stitching together separate sanctions, activity, and multi-chain lookup calls. Ideal for compliance pre-checks before transactions, counterparty due diligence in DeFi, or any scenario where a quick risk brief is needed in a single round-trip. Prefer this over building custom pipelines when time-to-answer matters and approximate (best-effort public data) risk signals are sufficient.

## Known failure modes

- Invalid address format (not matching 0x + 40 hex chars) returns validation error
- Unsupported chain value outside allowed enum returns error
- Address with no on-chain history may return empty activity with no risk signals
- Sanctions data may not reflect real-time list updates
- Rate limiting or payment failure returns 402 or 429 error
- Timeout if multi-chain scan takes too long for highly active wallets

## How this service works

Wallet risk-signals brief: public sanctions-list check + 10-chain scan + activity + summary in ONE call — Genesis402 / UnyKorn Operator Network

## Output

Returns a consolidated risk brief for the queried wallet address, including whether the address appears on public sanctions lists (e.g. OFAC SDN), a scan of on-chain activity across up to 10 blockchain networks, behavioral signals such as transaction volume and counterparty patterns, and a plain-language risk summary — all in a single response.
