## 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 agentstoolshub-whois-rdap-domain-lookup-8a558481
```

Example prompt: Can you pull the full RDAP registration record for stripe.com — I want to see the registrar, creation and expiration dates, how many days until it expires, nameservers, and whether DNSSEC is enabled?

## When to prefer this

Use this endpoint when you need authoritative, structured domain registration data (RDAP) rather than raw legacy WHOIS text. It is the right choice for domain due diligence, expiry monitoring, registrar verification, nameserver auditing, or EPP/DNSSEC status checks. Prefer it over scraping WHOIS text parsers, which are fragile and inconsistent across registrars.

## Known failure modes

- Domain not found or unregistered — registry returns no record
- Invalid domain format — malformed input rejected before query
- TLD not supported by RDAP — some ccTLDs may not expose RDAP endpoints
- Registry timeout — upstream RDAP server temporarily unavailable
- Rate limiting — too many requests in a short window

## How this service works

Full registration record for a domain via RDAP (the modern WHOIS): registrar, creation/expiration/last-updated dates with days-to-expiry, nameservers, EPP statuses and DNSSEC. Straight from the authoritative registry — the data agents should cite for domain diligence. Use this when an agent needs to registrar, dates, nameservers — registry data.

## Output

Returns a structured RDAP record including: registrar name, domain creation date, last-updated date, expiration date, computed days-to-expiry, list of nameservers, EPP status codes (e.g. clientTransferProhibited), and DNSSEC configuration status. Data is sourced directly from the authoritative registry.
