How this service works
15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).
Output
Returns a JSON object with a status field indicating success, a data object containing deliverability verdict, MX record details, SPF and DMARC configuration findings, and an roi_proof object showing compression/processing efficiency metrics.
Example use cases
B2B lead validation before outreach
“Before I import this list of prospect emails into my CRM, can you verify that ceo@techstartup.io is actually deliverable and has valid MX and SPF records set up?”
Onboarding email hygiene check
“A new user just signed up with the email address support@fakecompany.net — can you check if that email is real and the domain is configured to actually receive mail?”
Email infrastructure audit for a domain
“Can you check whether contact@globalventures.com has proper DMARC and SPF records in place, and whether the MX records are pointing somewhere legitimate?”
Technical details
Endpoint
GEThttps://agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email validation that also surfaces MX, SPF, and DMARC records in a single call — especially useful for B2B lead enrichment pipelines, agent-driven onboarding flows, or pre-send list hygiene where you want infrastructure-level detail beyond a simple format check. Prefer it over heavier email validation platforms when cost per call and USDC micropayment compatibility (x402) matter.
Side effects
- Missing or malformed email query parameter returns an error response
- Non-existent domain causes DNS lookup failure with appropriate error
- Temporary DNS resolution timeouts may yield inconclusive results
- Payment failure via x402/USDC results in HTTP 402 response and no data returned
- Disposable or catch-all domains may return ambiguous deliverability status
