## 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 jmt-x402-proxy-whois-rdap-domain-lookup-b69acf5f
```

Example prompt: Can you pull up the full RDAP registration record for stripe.com — I want to see the registrar, nameservers, and when it was registered?

## When to prefer this

Use this endpoint when you need structured, machine-readable RDAP domain registration data (registrar, dates, nameservers, status) for a specific domain — especially in automated workflows where you want JSON output rather than unstructured WHOIS text. Prefer this over generic WHOIS scraping when you need reliable structured output payable per-call via x402/USDC micropayments.

## Known failure modes

- Domain not found or unregistered — empty or null RDAP response
- Invalid domain format — may return a validation error
- Upstream RDAP registry unavailable — timeout or upstream error
- Missing required 'domain' query parameter — request rejected
- Payment not processed — x402 payment required error before response is returned

## How this service works

Raw RDAP registration record for a domain, returned as structured JSON.

## Output

A structured JSON object containing the domain name, the full raw RDAP record (registrar, registrant details, nameservers, registration dates, status flags, etc.), and a Unix timestamp of when the lookup was performed.
