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 the verification result for the queried email address, along with an roi_proof field showing a compression_ratio_pct indicating data efficiency.
Example use cases
Pre-send email list scrubbing
“Before I send this campaign, check if sarah.jones@startupco.io is a valid deliverable email — I don't want bounces hurting our sender reputation.”
Lead form submission validation
“Someone just filled out our contact form with the email temp123@mailinator.com — can you verify if that's a real address or a throwaway?”
CRM contact data cleanup
“I'm cleaning up our CRM and need to know if the email on file for this contact, m.rodriguez@oldcompany.net, is still valid and reachable.”

Side effects

- Temporary DNS lookup failures may produce inconclusive results
- Disposable or role-based addresses may be flagged or produce ambiguous results
