How this service works
Network, docs, image, web, and dev utility tools paid per call via x402. No signup, no API keys, no subscriptions — just USDC on Base.
Output
Returns a JSON object containing the host, port, certificate subject, issuer, and the not_before and not_after validity timestamps — enough to determine if the cert is valid, who issued it, and when it will expire.
Example use cases
Pre-deployment SSL expiry audit
“Check the SSL certificate on staging.myapp.com and tell me when it expires and who issued it — I want to make sure it won't expire before our launch next week.”
Custom port TLS inspection
“Can you look up the TLS certificate on mail.mycompany.com port 465 and give me the subject, issuer, and validity window?”
Third-party vendor certificate check
“I need to verify the SSL cert on my payment processor's domain api.paymentco.com — is it still valid and who's the issuer?”
Technical details
Endpoint
GEThttps://api.geekvault.dev/net-tools/v1/ssl-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-auth, pay-per-call TLS certificate inspection without setting up any SDK or API key. Ideal for agents that need to check certificate expiry or issuer on-demand for arbitrary hosts, especially when no persistent monitoring subscription is required.
Side effects
- Host unreachable or DNS resolution failure — connection error returned
- No TLS service on the specified port — connection refused or timeout
- Invalid hostname format — validation error
- Certificate could not be retrieved — server may not support TLS
