## 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 whatchuneed-whois-lookup-4f9537f9 -d '<json body>'
```

Example prompt: Can you run a WHOIS lookup on openai.com and tell me who registered it, when it expires, and which registrar they used?

## When to prefer this

Use this endpoint when you need programmatic WHOIS lookups for any domain via a simple pay-per-call API without needing to set up dedicated WHOIS infrastructure. Prefer this over manual WHOIS lookups or dedicated domain registrar APIs when you want a lightweight, on-demand lookup billed at $0.05 USDC per call via the x402 protocol.

## Known failure modes

- Domain not found or unregistered — result may be empty or return an error status
- WHOIS rate limiting or privacy protection (GDPR redaction) may hide registrant details
- Invalid or malformed domain input returns an error
- Timeout if WHOIS servers are slow to respond
- TLDs with non-standard or unsupported WHOIS servers may return incomplete data
