## 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-8233621a -d '<json body>'
```

Example prompt: Can you look up the RDAP registration info for openai.com — I want to see the registrar, when it was created and expires, and its nameservers?

## When to prefer this

Use this endpoint when you need structured, machine-readable RDAP domain registration metadata (registrar, dates, nameservers) without needing an API key or account. Prefer it over traditional WHOIS scrapers when you want a paid-per-call, deterministic lookup settled in USDC on Base, especially in agentic workflows where WHOIS parsing is unreliable.

## Known failure modes

- Domain not found or unregistered — returns empty or error response
- Invalid domain format in request string — may return validation error
- TLD not supported by RDAP bootstrap — incomplete or no data returned
- x402 payment failure — call not executed if USDC payment not settled
- Network timeout reaching upstream RDAP registry

## How this service works

Domain RDAP Lookup: RDAP domain lookup: registrar, dates, nameservers Executed deterministically by the AmanChain node against live consensus state (real blocks, pools, balances) — paid per call via x402, settled in USDC on Base. Input: JSON body {"serviceId":"aman-domain-info","request":"<input>"}. No account, no API key.

## Output

Returns structured RDAP domain data including the registrar name, domain creation date, last updated date, expiry/deletion date, current domain status flags, and authoritative nameservers for the queried domain.
