## 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 signaldesk-ai-whois-lookup-4fe0f905
```

Example prompt: Can you look up the WHOIS info for openai.com and tell me when it was registered, when it expires, and whether it's transfer-prohibited?

## When to prefer this

Use this endpoint when you need structured WHOIS data (registration status, creation/expiry dates, transfer flags) for a specific domain via a pay-per-call x402 micropayment model. Prefer this over manual WHOIS lookups or scraping when you need machine-readable output in an automated agent workflow at low cost ($0.005 per call).

## Known failure modes

- Domain not found or not registered — may return registered: false with limited fields
- Invalid domain format — likely returns a 400 or validation error
- Rate limiting or quota exhaustion — endpoint may return 402 or 429
- WHOIS data unavailable for certain TLDs or privacy-protected domains — partial data returned
- Payment failure — x402 payment not processed, endpoint returns 402

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

Returns a JSON object containing the queried domain name, its registration status (e.g. clientTransferProhibited), creation date, expiry date, and a boolean indicating whether the domain is currently registered.
