Ssl Checker X402

What is Ssl Checker X402?

Ssl Checker X402 checks SSL/TLS certificate validity, expiry, issuer, chain details, and security grade for any domain. It is a pay-per-call MCP server using the x402 micropayment protocol (USDC on Base L2) – no API key, no signup, and no rate-limit wall. Designed for AI agents and developers who need simple, programmatic certificate validation.

How to use Ssl Checker X402?

Add the server URL to your MCP client configuration (Claude Desktop, Cursor, ElizaOS, etc.). For direct HTTP access, send a POST request to /api/check with a JSON body containing the domain; the server returns a 402 payment challenge, which any x402‑aware client (e.g., @x402/fetch, x402-agent-tools) can resolve automatically. The single exposed tool is security_check_ssl.

FAQ from Ssl Checker X402

What is the difference between Ssl Checker X402 and other SSL checkers?

Traditional checkers often require signup or API keys; Ssl Checker X402 uses a pay‑per‑call micropayment model with no account needed. It is designed specifically for AI agents and one‑shot automation.

What runtime or dependencies are required?

No specific runtime beyond an MCP‑compliant client (e.g., Claude Desktop, Cursor) for the MCP interface, or any HTTP client able to handle the x402 payment challenge for direct HTTP usage.

Where does the SSL data come from and is it stored?

Data is fetched live from the target domain's SSL/TLS certificate at the time of each request. The server does not store certificate data after returning the response.

What are the known limitations of Ssl Checker X402?

It is only for SSL certificate checks. It does not perform DNS lookups, HTTP header analysis, or port scanning. A valid domain name must be provided.

How does authentication and transport work?

Transport: HTTPS (via MCP server URL or direct HTTP POST). Authentication: the x402 protocol sends a payment challenge (402 Payment Required) that the client must settle with USDC on Base L2 before receiving the certificate data. No API key or bearer token is used.
