## 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 util-beauty-rdap-lookup-9fab3a0a -d '<json body>'
```

Example prompt: Can you do an RDAP lookup on example.com and tell me who registered it, when it expires, and which registrar is handling it?

## When to prefer this

Choose this endpoint when you need structured, machine-readable domain or IP registration data (RDAP) without setting up your own DNS/RDAP client. Ideal for AI agents that need to resolve ownership or registration metadata on-demand, paying only per request via x402 USDC micropayments. Prefer over raw WHOIS when you need JSON-structured output and consistent formatting across registries.

## Known failure modes

- Domain or IP not found in RDAP registry — returns error or empty result
- Invalid input format (malformed domain or IP) — returns validation error
- RDAP registry timeout or unavailability — returns upstream error
- Insufficient credits or payment failure — returns 402 Payment Required
- Rate limiting if too many requests in a short window

## How this service works

Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.

## Output

Returns a JSON object with ok status, the utility name, a request ID, credits charged, and the full RDAP response for the queried domain, IP, or ASN — including registrant details, registration/expiry dates, registrar information, nameservers, and status flags.
