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 validity, deliverability, and format checks. A roi_proof field may also be included indicating data compression or processing efficiency metrics.
Example use cases
Pre-outreach email hygiene check
“Before I send my cold email campaign, can you verify that sarah.jones@prospectcompany.com is a real, deliverable address so I don't tank my sender reputation?”
CRM lead validation on signup
“A new lead just filled out our form with the email m.chen@techstartup.io — can you verify it's legitimate before we add them to our CRM and trigger the welcome sequence?”
B2B contact enrichment pipeline
“I'm building a prospect list and I need to check if the email address cto@bigenterprise.com actually exists and can receive mail — run a verification on it for me.”
Technical details
Endpoint
GEThttps://llms-generator.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, per-call email validation with micropayment billing (USDC via x402) and no subscription required. Useful for agents that need on-demand email hygiene without committing to a bulk verification SaaS plan. Part of the AgentDiet B2A hub, so it pairs naturally with other enrichment endpoints on the same platform (lead enrichment, domain OSINT, etc.).
Side effects
- Missing or malformed email query parameter returns an error
- Invalid email format may return a negative validation result
- Network timeouts or upstream service failures may return non-200 responses
- Payment failure via x402/HTTP 402 blocks access if USDC balance is insufficient
