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 the verification result for the queried email address, plus an roi_proof field indicating compression/distillation metrics.
Example use cases
Pre-outreach email validation
“Before I send my cold outreach campaign, can you check if contact@startupxyz.io is a real, valid email address I can actually reach someone at?”
Lead list quality cleanup
“I just imported a batch of leads and want to start with sarah.johnson@bigclient.com — can you verify that email is legitimate and deliverable before I add it to our CRM?”
User signup email check
“A new user just registered with the email free_user_99@tempmail.org — can you verify whether that's a real deliverable address or a throwaway?”
Technical details
Endpoint
GEThttps://defi-yield.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pay-per-call, no-subscription email verification check billed in USDC via HTTP 402 micropayments — especially useful for AI agents operating autonomously without a traditional API key billing relationship. Suitable for low-volume, on-demand verification within a broader B2A workflow alongside other AgentDiet intelligence tools.
Side effects
- Missing or malformed email query parameter returns an error
- Invalid email format may return a failed validation result
- Network or upstream provider timeout returns a non-ok status
- Payment failure via x402 prevents the request from being processed
