## 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 rdap-domain-registration-lookup-06912619
```

Example prompt: Can you pull up the RDAP registration data for stripe.com — I want to know who registered it, which registrar they used, and when it expires?

## When to prefer this

Use this endpoint when you need authoritative, structured domain registration data (RDAP format) including registrar, dates, nameservers, and status — preferred over raw WHOIS text parsing because RDAP returns clean JSON. Choose this when vetting domains for due diligence, monitoring expiry dates, investigating suspicious domains, or enriching domain intelligence pipelines. Not suitable if you need DNS resolution, SSL certificate info, or subdomain enumeration (see sibling endpoints for those).

## Known failure modes

- Domain not found or not registered returns an error or empty RDAP response
- Unsupported TLD may not have an RDAP endpoint, causing lookup failure
- Rate limiting by the upstream RDAP registry can cause timeouts
- Malformed domain name input may return a validation error
- Some registries redact all registrant contact info due to GDPR/privacy policies

## How this service works

Domain registration data (RDAP). ?domain=github.com

## Output

Returns structured RDAP JSON data for the queried domain, including registrar name, registration and expiration dates, domain status flags, nameservers, and where available, registrant/abuse contact details — sourced directly from the authoritative RDAP registry for that TLD.
