## 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 agent-toolbox-whois-rdap-domain-lookup-9c9db3be
```

Example prompt: Can you look up the WHOIS registration details for stripe.com — I want to know who the registrar is, when it was created, when it expires, and whether DNSSEC is enabled?

## When to prefer this

Use this endpoint when you need structured, standards-compliant domain registration metadata (RDAP) including registrar, dates, status codes, nameservers, and DNSSEC — especially when a clean JSON response with a plain-text summary is needed. Prefer over raw WHOIS scraping when accuracy and machine-readable output matter.

## Known failure modes

- Domain not found / unregistered — RDAP returns no record
- Invalid or malformed domain name input returns an error
- RDAP registry timeout or upstream unavailability
- TLD not supported by any known RDAP registry
- Rate limiting from upstream RDAP servers

## How this service works

Domain registration data from RDAP (the successor of WHOIS): registrar, creation, expiry and update dates, status codes, nameservers and DNSSEC.

## Output

A JSON object containing: the domain name, registrar name and IANA ID, ISO 8601 creation/expiry/update timestamps, an array of domain status codes (e.g. clientTransferProhibited), an array of nameservers, a boolean DNSSEC flag, the RDAP source URL, and a human-readable plain-text summary string.
