## 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 base-pulse-whois-lookup-eade62ba
```

Example prompt: Can you pull the WHOIS record for acmecorp.io? I want to see when it was registered, when it expires, who the registrar is, and what country the registrant is in before I proceed with this transaction.

## When to prefer this

Use this endpoint when you need quick, no-auth WHOIS data for any domain as part of due-diligence or counterparty verification workflows. It is ideal for AI agents that need to assess domain legitimacy, age, or registrar before authorizing a transaction. Prefer this over manual WHOIS lookups when automating trust checks in payment or onboarding pipelines.

## Known failure modes

- Domain not found or unregistered returns empty or error response
- WHOIS server rate-limiting may cause timeouts for rapid successive queries
- Some TLDs have privacy-protected or redacted WHOIS records returning minimal data
- Certain ccTLDs may not be supported by public WHOIS servers
- Network timeout if the upstream WHOIS server is slow or unresponsive

## How this service works

Returns structured WHOIS data for any domain: registrar name, creation date, expiry date, updated date, nameservers, and registrant country when available. Uses public WHOIS servers — no API key needed. Useful for due-diligence agents checking counterparty domains before a transaction.

## Output

A structured JSON object containing the domain's registrar name, creation date, expiry date, last-updated date, list of nameservers, and registrant country (when publicly available from WHOIS servers).
