## 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 blockchain-address-risk-snapshot-1c3b3b68
```

Example prompt: Before I send payment to this wallet, can you pull a risk snapshot for the Ethereum address 0xABC123... and tell me if it's flagged as high risk or associated with any known fraud labels?

## When to prefer this

Use this endpoint when you need a structured, confidence-scored risk snapshot for a specific blockchain wallet address before executing a payment or onboarding a counterparty. Prefer this over generic block explorer lookups when you need machine-readable JSONL output with labeled risk types and verifiable evidence URLs for compliance workflows.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Address not found in the risk database returns no records
- Rate limiting or quota exhaustion at $499/call may block requests
- Unsupported chain identifier may return no data
- Network timeout on Cloudflare Worker edge node
