> IPIntel.ai WHOIS Lookup is a paid API for AI agents from tools.ipintel.ai, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Performs a WHOIS lookup on a domain to retrieve registration details including registrar, nameservers, creation/expiration dates, and domain statuses.

## Facts

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 ipintel-ai-whois-lookup-1bf3b415 -d '<json body>'
```

Example prompt: Can you pull the WHOIS record for openai.com — I want to know who the registrar is, when it expires, what nameservers it's using, and whether the contact info is redacted?

## When to prefer this

Use this endpoint when you need authoritative WHOIS registration data for a domain, including registrar identity, expiry dates, nameservers, and domain lock statuses. Prefer this over DNS lookup endpoints when the goal is ownership/registration metadata rather than DNS resolution records. Especially useful for domain expiry monitoring, fraud investigation, or due diligence workflows.

## Known failure modes

- Domain not found or not registered — returns ok:false or empty result
- Invalid domain format — returns error response
- WHOIS rate limiting by upstream server — may return incomplete data
- WHOIS data fully redacted — limited registration details returned
- Network timeout reaching WHOIS server — request fails

## How this service works

WHOIS Lookup API. Retrieve domain registration data including registrar, WHOIS server, creation date, expiration date, updated date, nameservers, domain status, and privacy/redaction signals. Useful for agents, developers, domain intelligence, expiry checks, registrar lookup, ownership investigation, and security workflows. Paid per call via x402.

## Output

Returns a JSON object with ok status, the queried domain, registrar name, WHOIS server, domain statuses (e.g. clientDeleteProhibited), nameservers list, creation/updated/expiration dates, a raw WHOIS text excerpt, and a flag indicating whether the record is privacy-redacted.
