How this service works
Domain and email trust checks for AI agents. Domain: DNS, MX, SPF / DMARC / DKIM / MTA-STS / BIMI, DNSSEC, RDAP registration age + registrar + status, parking and disposable detection, risk flags, 0-100 score. Email: syntax, disposable / role / free provider, MX, domain auth, domain age, verdict. Public DNS + RDAP only; no SMTP probing; nothing stored.
Output
A JSON object containing: a 0-100 trust score and low/medium/high-risk verdict; DNS records (A, AAAA, NS, MX, CAA, CNAME, TXT count, DNSSEC validation); email security analysis (SPF policy and record, DMARC policy with subdomain and alignment settings, DKIM selector scan results, MTA-STS, TLS-RPT, BIMI presence, overall email grade); RDAP registration data (created date, expiry, registrar, domain status flags, age in days); parking and disposable domain flags; a list of risk flags with severity and penalty; and engine/query metadata.
Example use cases
Vendor onboarding fraud screening
“Before we process this invoice from payments-secure-hub.net, can you check if that domain is legit — how old it is, who registered it, whether it's parked or disposable, and what its overall trust score is?”
Phishing domain triage
“We got an email from support@customer-verify-login.com — can you run a domain trust check on customer-verify-login.com and tell me if it looks like a phishing domain, including its registration age and email security grade?”
Cold outreach sender verification
“I'm about to reply to a sales email from someone at accelerate-growth-partners.io — can you look up that domain and tell me if it's real, how long it's been registered, and whether it has proper DMARC and SPF in place?”
Technical details
Endpoint
GEThttps://domaincheck.agentgate.workers.dev/v1/domain?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal domain trust assessment in a single call — combining DNS health, email security posture, RDAP registration age/registrar, and a synthesized risk score. Prefer it over raw WHOIS lookups (no email security analysis), standalone DNS resolvers (no registration data or scoring), or email validation tools (no domain-wide risk verdict). Ideal for fraud screening, vendor onboarding, phishing triage, and outreach validation where a single trust verdict is needed quickly.
Side effects
- Domain not found or RDAP unavailable: registration.found=false, limited data returned
- Invalid domain input: 400 error or empty response
- DNSSEC validation failure: flagged in risk flags
- DNS timeout: partial DNS data returned, some record types missing
- DKIM selectors not discoverable: note returned explaining enumeration limitation
- Rate limiting or payment failure via x402 protocol: 402 or 429 response
