Whois Lookup

Looks up WHOIS registration data for a domain via the IANA-mandated RDAP endpoint for its TLD.

Overview

Looks up WHOIS registration data for a domain via the IANA-mandated RDAP endpoint for its TLD. Returns registration date, age in days, expiration date, days-until-expiry, last-changed and transfer dates, registrar (name + IANA id), registrant/admin/tech contacts, nameservers, DNSSEC-signed flag, EPP status codes, and risk flags (newly-registered, expiring-soon, locked). Optionally appends a crt.sh certificate-transparency summary. Use it as a whois API, RDAP domain lookup, domain age check, registrar finder, expiration checker, nameserver inspector, DNSSEC verifier, domain transfer history source, TLD registration record, or brand-protection + phishing triage tool.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/whois-lookup-162 \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/whois-lookup-162 \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
