## 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-457e0ab3
```

Example prompt: Can you look up the registration info for stripe.com — I want to know the registrar, when it was created, when it expires, and its current status?

## When to prefer this

Use this endpoint when you need authoritative domain registration metadata (registrar, dates, status, nameservers) for any given domain name. Prefer this over WHOIS-based tools when you need structured, machine-readable output. Best for domain due diligence, fraud detection, security research, and domain lifecycle monitoring.

## Known failure modes

- Domain not found or unregistered — RDAP returns no record
- TLD not supported by RDAP registry — lookup may fail
- Rate limiting from upstream RDAP registry — transient errors
- Malformed domain input — missing TLD or invalid characters
- RDAP registry temporarily unavailable — timeout or 5xx
