Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 whois-lite-via-rdap-b06151dc
```

Example prompt: Can you pull up the WHOIS registration info for openai.com — I want to know who the registrar is, when it was registered, when it expires, and what nameservers it's using?

## When to prefer this

Use this endpoint when you need fast, lightweight domain registration metadata (registrar, dates, nameservers, status) without full contact/registrant details. Prefer over full WHOIS scraping when only structural domain info is needed. Ideal for brand protection pipelines, security agents checking domain age/registrar, or outreach tools validating domain legitimacy. Use the sibling domain-bundle endpoint if you also need DNS and TLS info in one call.

## Known failure modes

- Domain not found in RDAP — returns ok: false or empty result
- Invalid domain format provided — query param validation error
- RDAP registry for the TLD unavailable — upstream timeout or error
- Rate limiting or upstream RDAP service outage — 5xx or timeout response

## How this service works

Domain registration status, registrar, dates, and nameservers via RDAP (lite fields only)

## Output

Returns a JSON object with fields: ok (boolean), domain (string), registrar (string), registration status, registration and expiry dates, nameservers, and the data source (RDAP service used). Lite fields only — no full contact records.
