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 verification status (ok), deliverability assessment, and metadata about the email address including whether the mailbox exists, domain is valid, and any risk signals. The response mirrors the hub's standard envelope with a data payload and status field.
Example use cases
Pre-send email list hygiene
“I have a list of leads and want to make sure their emails are valid before launching my cold email campaign — can you verify that sarah.jones@techstartup.io is deliverable and not a bounce risk?”
Real-time signup validation
“Someone just signed up with the email address free_user_99@mailinator.com — can you check if it's a legitimate address or a throwaway account I should flag?”
CRM data quality check
“We imported contacts from a trade show and I'm not sure the emails are accurate — can you verify whether mark.chen@globalpartners.com is a real, active mailbox?”
Technical details
Endpoint
GEThttps://email-verify-72343955726.us-central1.run.app/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email verification check without a subscription, particularly in agent workflows that need real-time validation at the point of data entry or lead enrichment. Best suited for single-address lookups via a micropayment model using x402/USDC, rather than bulk batch verification services.
Side effects
- Invalid or malformed email address input returns an error status
- Unresolvable domain results in domain-not-found or DNS failure signal
- Catch-all mail servers may return inconclusive deliverability results
- Rate limiting or payment failure (HTTP 402) if USDC payment is not attached
- Temporary SMTP timeouts may yield uncertain results for some providers
