Is this server for email validation?
No. This server audits deliverability (SPF, DKIM, DMARC, MX). Do not use it for email validation — use `email_verify_address`. Do not use it for email finding — use `email_find_by_name`.

概览
What is Email Deliverability X402?
Email Deliverability X402 is an MCP server that audits email domain deliverability by checking SPF, DKIM, DMARC, and MX records, returning a score from 0–100. It uses pay-per-call via the x402 protocol (USDC on Base L2), with no signup, API key, or rate-limit walls. It is part of the klymax402 marketplace of micropayment APIs for AI agents.
How to use Email Deliverability X402?
Configure the server in your MCP client (e.g., Claude Desktop, Cursor, ElizaOS) by adding the URL https://email-deliverability.api.klymax402.com/mcp to mcpServers. Then invoke the tool email_audit_deliverability with the required domain parameter (e.g., example.com). You can also call the HTTP endpoint directly with a curl command; any x402‑aware client handles the payment challenge automatically.
