## 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 gateway-stride20k-com-domain-whois-rdap-lookup-7401e179
```

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

## When to prefer this

Use this endpoint when you need authoritative, normalized domain registration data (dates, registrar, nameservers, DNSSEC, EPP status) sourced directly from the registry's RDAP server. Prefer over raw WHOIS scraping because output is structured JSON. Best for domain availability checks, expiry monitoring, ownership research, and security screening. If you need a full domain due-diligence report including DNS records and additional signals, use the companion domain due-diligence endpoint instead.

## Known failure modes

- Domain is unregistered or not found in RDAP — returns 404
- TLD not supported by any RDAP server — returns 404
- Domain name format is invalid — rejected by input validation
- Upstream RDAP server is unavailable — may return error or stale cache
- Rate limiting or payment failure — call blocked
- Some fields (registrar, dates) may be null if not published by the registry

## How this service works

Domain WHOIS/RDAP lookup API: registration data for any domain from the authoritative registry's RDAP server, normalized: registration/expiry/update dates, registrar, EPP status codes, nameservers, and DNSSEC. Works for all gTLDs and most ccTLDs. Unregistered or RDAP-less domains return an unpaid 404. Use for domain availability checks, ownership research, expiry monitoring, and security screening by agents. Cached up to 24 hours.

## Output

Returns a JSON object with the normalized domain name, array of EPP status codes, registration/expiry/last-updated dates in ISO 8601, registrar display name, list of nameserver hostnames, and DNSSEC boolean. Also includes metadata about whether the response was cached, when it was fetched, and the upstream source (RDAP). Returns 404 for unregistered or RDAP-unsupported domains.
