## 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 domain-rdap-lookup-domain-intelligence-nordman-tehau-workers-dev-bdea3fdc -d '<json body>'
```

Example prompt: Can you look up the RDAP registration details for example.com — I want to know the registrar, when it was registered, how old it is, when it expires, and what its current status is?

## When to prefer this

Use this endpoint when you need authoritative domain registration metadata — registrar, dates, age, status — from the modern RDAP protocol rather than legacy WHOIS. Prefer it over DNS lookup endpoints (which return resource records, not registration data) when the goal is ownership, age, or expiration information rather than IP addresses or mail server records.

## Known failure modes

- Domain not found or unregistered — RDAP returns empty or 404-equivalent response
- TLD not supported by RDAP — some ccTLDs may lack RDAP bootstrap entries
- Rate limiting or upstream RDAP registry timeout
- Invalid domain name format in request body
- Network error reaching the Cloudflare Worker or upstream RDAP server

## How this service works

## Output

Returns structured RDAP data for the queried domain including: registrar name, registration (creation) date, domain age, expiration date, and current domain status (e.g. active, suspended, pending delete).
