How this service works
Is this company real? Verify a company or domain is legitimate and established before your agent pays an invoice, onboards a vendor, or trusts it. A KYB (know your business) and due-diligence oracle for vendor screening, supplier checks and fraud review: RDAP domain registration age, DNS (A/MX/NS), email posture (SPF/DMARC), HTTPS reachability. Flags newly registered or thin-infrastructure domains. Returns a signed attestation, 0-100 trust score, evidence URLs. Bulk: /verify/business/batch.
Output
A signed attestation object containing a 0-100 trust score, domain registration age (via RDAP), DNS record findings (A, MX, NS), email security posture (SPF and DMARC status), HTTPS reachability result, and evidence URLs supporting each check.
Example use cases
Invoice fraud prevention before payment
“We just got an invoice from globalparts-vendor.net — before I approve the wire transfer, can you verify whether that domain is real and established? I need the trust score, how old the domain is, and whether their email security looks legitimate.”
New supplier onboarding vetting
“We're about to onboard nexalogistics.com as a vendor. Can you check if they're a real, established business — look at their domain age, DNS setup, SPF and DMARC records, and give me a signed trust score before we proceed?”
Marketplace seller legitimacy check
“A seller on our platform is using the domain craftpro-goods.co — can you verify it's a legitimate business with real DNS, working email security, and a reachable HTTPS site, and tell me what trust score it gets?”
Technical details
Endpoint
POSThttps://402oracle.com/verify/business?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to vet a business domain before making a payment, onboarding a vendor, or trusting an invoice — especially when you need a signed, evidence-backed attestation rather than a raw lookup. Prefer this over generic WHOIS tools when you need a composite trust score combining domain age, DNS health, email security, and HTTPS reachability in a single verifiable response. Ideal for autonomous payment agents operating under the x402 protocol.
Side effects
- Domain does not exist or has no RDAP record — low trust score returned with missing evidence
- HTTPS endpoint unreachable — reachability check fails, score penalized
- DNS records absent or misconfigured — flagged in attestation
- Invalid or malformed domain input — request rejected with validation error
- Payment not received or insufficient USDC — 402 payment required error
- Rate limiting or timeout on external DNS/RDAP lookups — partial result or retry needed
