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 ('ok') and a data object containing email verification results such as format validity, domain MX record existence, mailbox reachability, and disposable/role-based address flags. An roi_proof field with compression_ratio_pct may also be included.
Example use cases
Pre-send email list hygiene
“Before I launch this cold email campaign, check if sarah.jones@techstartup.io is a valid deliverable inbox so I don't tank my sender reputation.”
CRM lead validation on intake
“We just got a new lead from a web form with the email m.rodriguez@globalventures.com — can you verify it's a real address before our sales team spends time on it?”
Detecting fake signups
“Someone signed up with throwaway123@mailnull.com — can you check if this is a disposable or fake email address so I know whether to block the account?”
Technical details
Endpoint
GEThttps://sec-intel.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, per-email verification at $0.005 USDC per call with micropayment via x402 Base USDC, especially within an agent pipeline that already uses the AgentDiet B2A suite for lead enrichment, OSINT, or SEC/GitHub intelligence. Prefer it for agentic workflows that need pay-per-use email validation without subscription overhead.
Side effects
- Missing 'email' query parameter — returns error or empty data
- Invalid email format submitted — may return format validation failure
- Domain has no MX records — reported as undeliverable
- SMTP verification blocked by target server — inconclusive result
- Payment not completed via x402/USDC — HTTP 402 returned, request blocked
