How this service works
Paid per-call web tools for AI agents: DNS, TLS, robots.txt, hashing, JavaScript rendering and screenshots. Payment over x402 (USDC on Base).
Output
Returns a JSON object with the hostname and port checked, a boolean indicating whether the certificate chain is verified and within its validity window, the cipher suite, issuer name, subject name, days remaining until expiry, the expiry datetime, TLS version string, count of Subject Alternative Names, and a sample list of SANs. On error, an error field is included instead.
Example use cases
Certificate expiry monitoring for production services
“Check the TLS certificate for payments.mycompany.com — I need to know if it's still valid and how many days we have left before it expires so I can schedule a renewal.”
Security audit of a third-party vendor
“I'm vetting a new vendor before we integrate with them. Can you pull the TLS certificate details for vendor-api.example.com and tell me the issuer, TLS version, and cipher they're using?”
Debugging a certificate chain error
“Our app is throwing TLS errors when connecting to data.partner.io — can you check if the certificate is valid and whether there are any obvious issues like expiry or a bad chain?”
Technical details
Endpoint
GEThttps://49112-hjhjtioxvirqvcvo.splox.app/tls-certificate?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically check TLS certificate health, expiry countdown, issuer trust, or cipher/TLS version details for any hostname — particularly useful for automated certificate monitoring, security audits, or pre-integration vendor checks. Prefer this over manual curl-based inspection when you need structured, machine-readable output at low cost ($0.0005 per call) with x402 micropayment support.
Side effects
- Host unreachable or DNS resolution failure returns an error field
- Invalid or malformed hostname returns an error
- Host does not support TLS on port 443 returns an error
- Self-signed or unrecognized CA returns valid=false
- Expired certificate returns valid=false with days_left <= 0
- Network timeout from the service side returns an error field
