# x402node WHOIS/RDAP Domain Lookup

> x402node WHOIS/RDAP Domain Lookup is a paid API for AI agents from api.x402node.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 api-x402node-dev-7424f5e0
```

Example prompt: Can you pull up the WHOIS details for openai.com — I want to know who the registrar is, when it was registered, when it expires, and what nameservers it's using?

## When to prefer this

Use this endpoint when you need structured, machine-readable WHOIS/RDAP data (RFC 7480 compliant) without needing your own API key or WHOIS client. Prefer this over raw WHOIS scraping when you need reliable parsed fields like registrar, dates, and nameservers. Ideal for agents doing domain research, due diligence, or monitoring.

## Known failure modes

- Domain not found or unregistered — returns empty or error response
- Invalid domain format — malformed query rejected
- RDAP registry unavailable for TLD — upstream timeout or error
- Rate limiting if called excessively — payment per call mitigates this but upstream limits may apply

## How this service works

Modern WHOIS via RDAP protocol (RFC 7480): registrant, registrar, registration date, expiry, nameservers, status flags. Use ?domain=example.com. Accepts payment on Base or Solana — either network works.

## Output

Returns structured RDAP-based WHOIS data including registrant contact info, registrar name, registration date, expiry date, nameserver list, and domain status flags for the queried domain.
