## 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 suverse-rdap-domain-lookup-59d0305c -d '<json body>'
```

Example prompt: Can you pull up the RDAP registration data for openai.com — I need the registrar, current status, nameservers, and when it was registered and expires?

## When to prefer this

Choose this endpoint when you need structured, machine-readable domain registration metadata without setting up WHOIS parsing or managing API keys. It is ideal for AI agents performing domain due diligence, fraud signal checks, or domain asset audits where you need registrar, status, nameservers, and lifecycle dates in a clean JSON format. Prefer this over raw WHOIS when you want consistent structured output and RDAP protocol compliance.

## Known failure modes

- Domain not found — RDAP returns a 404-equivalent if the domain does not exist or has never been registered
- TLD not supported — some ccTLDs may not have RDAP coverage and will return no data
- Malformed domain input — invalid domain strings may result in errors
- Rate limiting — underlying RDAP registries may throttle repeated queries for the same domain
- Redacted data — some registrar records redact registrant contact info per GDPR/privacy policies

## How this service works

Structured domain registration data over RDAP, the modern WHOIS replacement, no key. Returns registrar, status, nameservers, and key event dates. For AI agents doing domain due diligence, fraud checks, and asset inventory.

## Output

Returns structured RDAP data for the queried domain, including registrar name and IANA ID, domain status codes (e.g. clientTransferProhibited, active), nameserver hostnames, and key event dates such as registration date, last updated date, and expiration date.
