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 'data' field containing email verification results (validity, deliverability, domain checks), a 'status' field indicating success or failure, and an 'roi_proof' object showing compression efficiency metrics.
Example use cases
Pre-send email list cleanup
“I've got a list of leads and I want to check if sarah.jones@techcorp.io is a real, deliverable email before I send our campaign — can you verify it?”
Onboarding user email validation
“A new user just signed up with the email mike_test_123@freemail.net — can you verify that it's a real address before we create their account?”
Sales CRM lead enrichment
“I'm about to reach out to a prospect at contact@startupxyz.com — can you confirm that email is valid and won't bounce?”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call email validation that charges fractions of a cent per check, especially in agent pipelines that require micropayment-native (x402/USDC) infrastructure. Suitable for lead enrichment, onboarding flows, or pre-send list hygiene where you need a lightweight single-email check without a subscription plan.
Side effects
- Missing or malformed 'email' query parameter — returns error status
- Invalid email format — returns invalid/unverifiable result
- Domain does not exist or has no MX records — returns undeliverable
- Payment not provided or insufficient — HTTP 402 with x402 payment challenge
- Rate limiting or quota exceeded — returns error response
- Disposable or catch-all email domains may return uncertain results
