## How to call it through Zero

```sh
zero fetch --capability geekvault-whois-lookup-005447de
```

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

## When to prefer this

Use this endpoint when you need quick, no-signup WHOIS data for any hostname or domain and want to pay per call via USDC without managing API keys or subscriptions. It is ideal for agents that infrequently need WHOIS lookups and prefer micro-payment-based access over monthly subscriptions.

## Known failure modes

- Invalid or unresolvable host returns an error
- WHOIS rate limiting by upstream registries may cause failures
- Private/redacted WHOIS records may return minimal registrant info
- Non-existent domains may return empty or error responses
- Network timeouts for slow WHOIS servers

## How this service works

Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.

## Output

Returns a JSON object containing the queried host and the raw WHOIS record text as a string. The raw field includes the full plaintext WHOIS response from the registry, which typically contains registrar name, registration and expiry dates, registrant contact info, name servers, and status codes.
