NAME

ssl-certificate-check — check a domain's current tls certificate without opening a raw socket

synonym alias of ssl-cert-info — reuses the canonical handler.

SYNOPSIS

POST https://x402.agentutility.ai/ssl-certificate-check
     Content-Type: application/json
     X-PAYMENT:    <signed-transferWithAuthorization>

     { ... }

↳ first call → 402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.

DESCRIPTION

Check a domain's current TLS certificate without opening a raw socket. Send a host and it queries Certificate Transparency logs (crt.sh, with a Cert Spotter fallback) to return the active certificate's issuer, subject, SAN list, validity window, days_until_expiry, signature algorithm, and key size; pass history:true to also get past certificate entries. Use it as an SSL certificate checker, TLS certificate expiry API, cert transparency lookup, or domain HTTPS monitoring tool for catching certs before they lapse or auditing who issued a site's TLS cert.

INPUT — request schema

property	type	description	req?
host	string	Hostname to inspect, e.g. 'example.com'. Normalized (scheme/port stripped).	required
history	boolean	Include up to 50 historical certificates for the host. Optional, default false.	optional

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/ssl-certificate-check \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the ssl-certificate-check tool from your MCP-aware agent.

MCP server handles payment automatically — your coding agent just calls the tool by name.
