How this service works
SSL/TLS certificate intel for any domain via Certificate Transparency. Paid per call: $0.002 USDC on Base, Monad, Arbitrum, Optimism, Polygon, Avalanche or Solana (eip155:8453) via x402 v2. No API key.
Output
Returns SSL/TLS certificate metadata for the queried domain, sourced from Certificate Transparency logs. Typically includes certificate issuer, subject, validity period (not-before and not-after dates), certificate serial number, and possibly Subject Alternative Names (SANs) and certificate chain details.
Example use cases
Pre-launch security audit
“Before we go live, check the SSL certificate on ourbrand.com — I need to confirm it's valid, see who issued it, and make sure it doesn't expire in the next 90 days.”
Phishing domain investigation
“I think suspicious-login-page.com might be a phishing site — can you pull its SSL certificate details so I can see who issued it and when it was registered?”
Certificate expiry monitoring
“Check the SSL certificate for api.myservice.io and tell me the exact expiration date so I can schedule a renewal reminder.”

Endpoint
GEThttps://ssl-info.hsharmanov02.workers.dev/ssl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, no-API-key SSL/TLS certificate intelligence for any domain, especially for one-off lookups or agent workflows that need certificate validity, issuer, and expiry data sourced from Certificate Transparency logs. It's well-suited for security audits, phishing investigation, and expiry monitoring where a per-call micro-payment model (via x402 on Base/Solana/Polygon/etc.) is acceptable and no credential setup is desired.
Side effects
- Domain not found or no certificate transparency records available — returns empty or error response
- Invalid domain format input — likely returns a 4xx error
- Domain with no SSL certificate (HTTP only) — may return empty result or error
- Network timeout reaching the Certificate Transparency backend
- Rate limiting or payment failure via x402 protocol
