SSL Checker API

Gives Claude tools to check SSL/TLS certificates for any domain. You get validity status, expiration dates, issuer information, certificate chain details, and security grades. Runs as a remote service at ssl-checker.api.klymax402.com and uses x402 micropayments, so you'll need to handle payment tokens for API calls. Useful when you're auditing domains, monitoring certificate health across infrastructure, or need to verify SSL configs without manually opening browsers or running openssl commands. The repository is pretty bare, just the MCP wrapper code without much documentation on the x402 payment flow or available tool schemas.
