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. Also includes an roi_proof field with a compression_ratio_pct metric.
Example use cases
Pre-send email list cleanup
“Before I kick off this email campaign, can you verify that sarah.johnson@techcorp.io is a valid deliverable address so we don't waste sends on bad contacts?”
B2B lead enrichment validation
“I just scraped a lead's email as m.chen@globalventures.com — can you verify it's real and deliverable before I add it to our CRM?”
Signup fraud prevention check
“Someone just signed up with the email disposable123@mailnull.com — can you check if that's a real address or a throwaway so I can flag the account?”
Technical details
Endpoint
GEThttps://email-verify.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-use email validation check via USDC micropayment (x402/HTTP 402) without a subscription. It is well-suited for B2B lead enrichment pipelines, pre-campaign list cleaning, or fraud detection at signup where per-call pricing is more economical than bulk SaaS plans.
Side effects
- Missing or malformed email query parameter returns an error
- Invalid email format may return a negative validity result rather than an error
- Network timeouts if the target email domain is slow to respond
- Payment failure (HTTP 402) if USDC balance is insufficient for the $0.005 per-call fee
- Unknown or non-existent domains may produce uncertain deliverability results
