Common questions about connecting and running SSL Checker API.
What SSL certificate information does this server provide?
It returns certificate validity status, expiry dates, issuer details, the full certificate chain, and a security grade. This helps you monitor certificate health and catch expirations before they cause downtime.
How do I authenticate and set up this MCP server?
The server uses x402 micropayment authentication. Connect via the SSE transport endpoint at https://ssl-checker-x402-production.up.railway.app/mcp and provide the required x402 credentials in your MCP client configuration.
What does the x402 micropayment model mean for pricing?
x402 is a micropayment protocol for pay-per-use API access. Each SSL certificate check incurs a small charge; refer to the x402 provider's pricing for exact rates.
Can I check multiple domains or run bulk certificate audits?
The registry metadata does not specify bulk or batch capabilities. Check the hosted endpoint documentation or test with individual domain queries; you may need to loop requests in your client.
What's the difference between this and free SSL checkers like SSL Labs?
This MCP server integrates certificate checking into your AI workflow via the Model Context Protocol, enabling automated audits and real-time alerts. Free tools are manual; this is programmatic and designed for developer automation.
