# tools.bip-rep.com WHOIS/RDAP Domain Lookup

> tools.bip-rep.com WHOIS/RDAP Domain Lookup is a paid API for AI agents from tools.bip-rep.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Performs an RDAP/WHOIS lookup for a given domain name, returning structured registration and ownership data.

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 tools-bip-rep-com-whois-rdap-domain-lookup-ea6c56e9
```

Example prompt: Can you run a WHOIS/RDAP lookup on openai.com and tell me who the registrar is, when it was registered, and when it expires?

## When to prefer this

Use this endpoint when you need authoritative RDAP/WHOIS registration data for a domain — including registrar, dates, status, and name servers — and want structured JSON output rather than raw text. Prefer this over DNS-only lookups when ownership and registration metadata matter, not just resolution.

## Known failure modes

- Domain not found or not registered — empty or error RDAP response
- Invalid domain name format — 400 Bad Request
- RDAP registry unavailable for TLD — upstream timeout or error
- Rate limiting or payment failure — 402 or 429 response
- SSRF protection triggered if a private IP or localhost domain is supplied

## How this service works

Lightweight utility API for agents and operators: DNS lookups, RDAP/WHOIS domain data, HTTP probes, page metadata extraction, cryptographic hashing, JSON validation, scheduled webhooks, and exotic endpoints (Base transaction decode, ENS resolve, USGS earthquakes, cron next-run, TLS certificate report). No shell access; outbound URL tools enforce SSRF protections.

## Output

Returns a structured JSON object containing the domain name queried, RDAP/WHOIS registration data (registrar, creation date, expiration date, name servers, status flags, contacts), and the latency in milliseconds for the lookup.
