## 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 tokenguard-whois-domain-lookup-2882655c -d '<json body>'
```

Example prompt: Can you look up the WHOIS record for example.com — I want to know when it was created, when it expires, who the registrar is, and what nameservers it uses?

## When to prefer this

Use this endpoint when you need structured, machine-readable WHOIS/domain registration data including creation, expiration, registrar, and nameservers — especially in a crypto/DeFi or AI agent context where x402 micropayment billing ($0.005/call) is already in use and you want WHOIS data as part of a broader on-chain or web intelligence workflow.

## Known failure modes

- Domain not found or does not exist — likely returns an error or empty result
- Invalid domain format — malformed input may return a validation error
- WHOIS data unavailable for certain TLDs — some domains have restricted WHOIS data
- Rate limiting or payment failure — x402 micropayment not accepted or insufficient funds
- Timeout if the upstream WHOIS registry is slow or unreachable

## How this service works

Domain registration facts over RDAP (structured WHOIS): registrar, creation and expiry dates, status codes, nameservers

## Output

A JSON object containing the domain's creation date (ISO 8601), expiration date (ISO 8601), registrar name, and an array of nameserver hostnames. For example: {"domain":"example.com","created":"1995-08-14T04:00:00Z","expires":"2026-08-13T04:00:00Z","registrar":"RESERVED-IANA","nameservers":["a.iana-servers.net"]}.
