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 structured JSON object containing DNS records, TLS certificate details, RDAP/WHOIS registration data (including domain age in days), hosting information, mail security configuration, risk signals array, entity hints, source URL, and a signed receipt confirming the lookup.
Example use cases
Vendor onboarding domain check
“Before we onboard this new supplier, can you run a domain due diligence check on acme-supplies.io — I want to see how old the domain is, who hosts it, and whether there are any red flags?”
Phishing domain investigation
“We got a suspicious email from someone at secure-payments-verify.com — can you look up that domain and tell me the DNS records, domain age, TLS info, and any phishing risk signals?”
Mail security audit for a counterparty
“Check the domain techpartner.de for me — specifically I need to know if they have SPF, DKIM, and DMARC set up correctly and what their MX records look like.”
Technical details
Endpoint
POSThttps://agosint.shveik.dev/v1/mpp/domain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, multi-source domain intelligence in a single call — combining RDAP/WHOIS, DNS, TLS, hosting, and mail security data — especially for vendor due diligence, KYB workflows, or phishing investigation. Prefer this over raw WHOIS lookups when you need signed, agent-ready JSON output with risk signals and no account setup required.
Side effects
- Invalid or malformed domain name returns a validation error
- Domain not found in RDAP/WHOIS returns empty or partial records
- TLD not covered by RDAP falls back to WHOIS with potentially less structured data
- Network timeout reaching upstream registries returns a partial result or error
- Stablecoin payment failure or insufficient balance returns 402 Payment Required
