## How to call it through Zero

```sh
zero fetch --capability ai-rook-whois-lookup-0b96f4c4
```

Example prompt: Can you look up the WHOIS record for ai-rook.com and tell me when it was registered, when it expires, and who the registrar is?

## When to prefer this

Use this endpoint when an agent needs to retrieve domain registration metadata (registrar, dates, nameservers) without an API key or signup, paying only $0.005 USDC per call via x402 on Base mainnet. Prefer this over free WHOIS APIs when operating in a crypto-native, pay-per-call agent commerce context or when you need programmatic access without rate-limit concerns tied to authentication.

## Known failure modes

- Domain not found or unregistered — likely returns empty or error response
- Invalid domain format — malformed input may return 4xx error
- WHOIS data unavailable for certain TLDs or privacy-protected domains
- Rate limiting or payment failure on x402 — 402 Payment Required if USDC payment not provided
- Stale or cached WHOIS data may not reflect very recent registration changes
