## 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 agentutility-vendor-domain-risk-check-36102417 -d '<json body>'
```

Example prompt: Before we onboard stripe.com as a payment vendor, can you run a domain risk check on them — I want to know the domain age, any risk flags, and who the registrar is?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call vendor domain risk assessment with domain age and registrar metadata — especially useful in automated vendor onboarding flows, supply-chain due diligence, or fraud screening pipelines where you need structured risk signals without subscribing to a full threat-intel platform.

## Known failure modes

- Invalid or malformed domain name input returns an error
- Domain not found in registry returns empty or null results
- Payment failure (402) if USDC balance is insufficient
- Rate limiting or quota exceeded
- Network timeout for newly registered or obscure TLDs

## How this service works

Paid x402 endpoints organized into product clusters. USDC-settled on Base. MCP-callable. ERC-8004 identity registry agentId 47167.

## Output

Returns a JSON object with a list of risk flags (empty array if none), the queried domain, domain age in days, and registrar details including name. For example: {flags: [], domain: 'stripe.com', age_days: 1860, registrar: {name: 'Example Registrar'}}
