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 verification details about the email address (validity, deliverability, domain checks), and an roi_proof field showing compression or processing efficiency metrics.
Example use cases
Pre-send email list cleanup
“I have a list of leads and I want to check if contact@startupxyz.io is a valid deliverable email before I send them a cold outreach — can you verify it?”
Sign-up form fraud prevention
“A user just registered with the email temp_user_99@mailinator.com — can you verify if that's a real or disposable address so I can decide whether to flag the account?”
CRM data hygiene check
“We're cleaning up our CRM and I need to know if sales@oldcompany.com is still a valid mailbox — can you run a verification on it?”
