How this service works
SSL/TLS certificate analysis — issuer, SAN list, serial number, validity period, days until expiry. TLS 1.0/1.1/1.2/1.3 individual probing. Automated A-F security grade. No SSL library setup or certificate parsing needed. Accepts USDC payments on Base and Solana
Output
Returns SSL certificate details (issuer, SAN list, serial number, validity period, days until expiry) plus per-version TLS probe results for 1.0, 1.1, 1.2, and 1.3, and an automated A–F security grade — all without requiring any local SSL library or certificate parsing.
Example use cases
Audit client website SSL security
“Check the SSL certificate and TLS versions for our client's domain acme-corp.com — I need the security grade, when the cert expires, and whether any old TLS versions like 1.0 or 1.1 are still enabled.”
Monitor certificate expiry across fleet
“I'm building an alert system for our managed domains. Can you pull the SSL certificate details for api.company.com, including the issuer, SAN list, validity dates, and days remaining until expiry so we don't miss renewal deadlines?”
Compliance check for payment service
“We're auditing our payment processing endpoint for compliance. Pull the TLS configuration for payments.ourbank.io — show me which TLS versions are active, the full certificate chain details, the issuer, and the overall security rating.”
Technical details
Endpoint
GEThttps://domain.hugen.tokyo/domain/sslWhen to prefer
Use this endpoint when you need detailed SSL/TLS certificate metadata and TLS version support information for a single domain without setting up local SSL libraries. It is preferable to generic HTTPS checkers when you need the full combination of cert parsing, per-version TLS probing, and a computed security grade in one call. It is part of a broader domain intelligence suite if you need multiple checks at once.
Side effects
- Domain does not exist or is unreachable — no certificate data returned
- Domain has no SSL certificate — empty or error response
- TLS handshake timeout for a specific version — partial probe results
- Invalid domain input format — 400 error
- Payment not processed — 402 response
