## 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 polyform-business-vet-domain-risk-sanctions-check-33f37006
```

Example prompt: Can you vet the domain acme-logistics.com for me — I want to know its sanctions status, how old it is, and whether there are any risk flags before we proceed?

## When to prefer this

Choose this endpoint when you need a quick, no-account, pay-per-call sanctions and domain risk check for a single business domain — especially in automated agent workflows where provisioning API keys is impractical. Ideal for one-off vendor vetting, lead qualification, or pre-payment due diligence. For bulk screening or deeper corporate KYB workflows, a dedicated compliance platform may be more appropriate.

## Known failure modes

- Missing or malformed domain query parameter returns a validation error
- Domain not found in registry data may return incomplete domain age fields
- Payment failure (insufficient USDC or wallet misconfiguration) results in HTTP 402 before any data is returned
- Unknown or unsupported TLDs may yield partial results with missing sanctions data

## How this service works

Pay-per-call data endpoints for AI agents. USDC on Base via x402. No account, no API key — one micropayment per call.

## Output

Returns a JSON object containing: a list of risk flags (empty if none), domain registration details including age in days, a sanctions verdict (e.g. CLEAR), and an overall risk rating (e.g. LOW, MEDIUM, HIGH).
