How this service works
Pay-per-call AI/data tools settled in USDC on Base via x402. No account, no API key — pay the 402 and receive the result. All endpoints also accept a bare hostname without the https:// prefix.
Output
Returns a JSON object with: DNS records (A, MX, NS, TXT), RDAP data (registrar name, creation date, expiry date, status flags), the queried domain string, and certificate transparency data from crt.sh (total certificate count, earliest issuance date, latest issuance date).
Example use cases
Vetting a new vendor domain
“Before we wire money to this supplier, can you check out their domain procurex-global.com? I want to know when it was registered, who the registrar is, whether it's about to expire, and if it has any real certificate history.”
Investigating a phishing suspect
“A user reported a suspicious email from billing-secure-update.net — can you pull the DNS records, RDAP info, and cert transparency data on that domain so I can figure out if it's a legit site or a fresh phishing domain?”
Pre-partnership domain due diligence
“We're about to sign a contract with a company at partnerventures.co — can you look up their domain registration details, nameservers, MX setup, and SSL certificate history so I can do a quick due diligence check?”
Technical details
Endpoint
POSThttps://fitze-x402-seller.app.workbuddy.host/tools/domain_intel?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap ($0.02), no-signup domain vetting call that bundles DNS, RDAP registration metadata, and certificate transparency history in a single response. It is ideal for fraud detection pipelines, vendor due-diligence agents, and security triage workflows where you want correlated domain signals without stitching together multiple APIs. Prefer alternatives if you need bulk/batch domain lookups, WHOIS full-text output, real-time threat-intelligence feeds, or geolocation of the domain's IPs.
Side effects
- Domain does not exist or has never been registered — RDAP and DNS fields may be empty or null
- Domain is under RDAP privacy/redaction — registrar details may be incomplete
- crt.sh lookup fails or returns no results for a newly registered or obscure domain
- Invalid domain format supplied — validation error returned
- Upstream DNS resolver or RDAP registry is temporarily unavailable — partial results or timeout
