How this service works
Company and domain due diligence for AI agents: official registers, sanctions lists and domain records, signed. Pay per call in stablecoins, no account.
Output
Returns a JSON object containing: DNS records, TLS certificate information, RDAP/WHOIS registration data, domain age in days, hosting provider signals, mail security records (SPF/DKIM/DMARC), entity hint, source URL, schema identifier, and a signed receipt confirming the lookup.
Example use cases
Vendor domain verification before onboarding
“We're about to start working with a supplier whose domain is globaltradepartners.net — can you check how old the domain is, who registered it, and whether the DNS and mail security look legitimate?”
Phishing domain triage for security team
“We received an email from invoice-payments-secure.com and I'm suspicious it might be a phishing domain. Can you pull the RDAP registration data, domain age, and hosting signals for it?”
Counterparty due diligence in a contract deal
“Before we sign with this company, can you look up their domain zetafinancialgroup.io and give me their DNS setup, TLS cert details, how long the domain has been registered, and any red flags?”
Technical details
Endpoint
POSThttps://agosint.shveik.dev/v1/x402/domain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, signed domain intelligence covering DNS, TLS, RDAP registration, domain age, hosting, and mail security in a single call — especially for vendor due diligence, KYB workflows, or phishing risk assessment. Prefer over generic WHOIS tools when you need machine-readable, agent-ready output with a payment receipt. Choose the sibling 'domain intelligence and phishing-risk signals' endpoint if you need a more phishing-focused signal set rather than general registration and infrastructure data.
Side effects
- Domain not found in RDAP/WHOIS — returns empty or partial records
- Invalid domain format (exceeds 253 chars or malformed) — validation error
- RDAP registry unavailable for TLD — partial data returned
- TLS lookup failure if domain has no HTTPS — TLS field may be empty
- Payment not settled — 402 response blocking the call
