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 email verification results including validity status, deliverability assessment, domain health, and risk signals such as whether the address is disposable, a catch-all, or likely to bounce. Also includes token-efficiency metadata (roi_proof) showing compression ratio and tokens saved.
Example use cases
B2B lead list hygiene
“I have a list of prospect emails from a trade show — can you check whether sales@innovatetech.io is valid and deliverable before I start my email campaign?”
Catching fake signups
“Someone just signed up with the email throwaway123@mailinator.com — can you verify if it's a disposable or fake address so I can decide whether to approve their account?”
CRM data quality check
“Before I import this contact into our CRM, can you validate that cto@startupxyz.com is a real, working email address and not going to bounce?”
Technical details
Endpoint
GEThttps://arxiv-digest-72343955726.us-central1.run.app/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, affordable per-email verification at $0.005 USDC per call with native HTTP 402 micropayment support (x402 Base USDC), especially within an agent workflow already using the AgentDiet B2A suite for lead enrichment, domain OSINT, or B2B intelligence. Prefer it when you want agent-native, pay-per-use email validation without managing API key subscriptions.
Side effects
- Invalid or malformed email address input returns an error status
- Domain does not exist or has no MX records, flagged as undeliverable
- Rate limiting or quota exceeded on the USDC micropayment tier
- Payment via x402/HTTP 402 not completed, request rejected
- Temporary DNS lookup failures causing inconclusive results
