How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
Returns a JSON object with a status field ('ok') and a data object containing the verification result, plus an roi_proof field indicating compression efficiency. The data object holds the actual email validation details such as validity, deliverability, and format checks.
Example use cases
Pre-send email list cleanup
“Before I send out this campaign, can you check if sarah.jones@companyxyz.com is a valid email address so I don't get a bounce?”
New user registration validation
“A user just signed up with the email address test123@fakeDomain.net — can you verify it's real and deliverable before I create their account?”
CRM data hygiene check
“I have this contact email bob.smith@oldcorp.org in my CRM — can you verify whether it's still a valid address?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a pay-per-use, crypto-settled (USDC on Base) email verification call without a subscription to a dedicated email validation service. It is well-suited for AI agents operating in agentic workflows that already use x402 payment rails, MCP tooling, or need lightweight email validation as part of a larger automated pipeline.
Side effects
- Missing email query parameter returns an error response
- Invalid or malformed email string may return a negative validation result
- Payment failure via x402/USDC settlement blocks the request
- Network timeout from upstream verification provider
- Rate limiting if too many requests are made in quick succession
