How this service works
Call when an agent needs a certificate summary for TCP 443. ok_check is true when the cert is authorized and unexpired. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/tls-https first.
Output
Returns a certificate summary for the given host on TCP port 443, including an ok_check boolean that is true when the certificate is both authorized (trusted) and unexpired, along with supporting certificate metadata.
Example use cases
Pre-deployment HTTPS cert check
“Before we launch, can you verify that the TLS certificate for staging.myapp.io is authorized and unexpired so we know HTTPS is properly set up?”
Monitor partner API certificate health
“Check whether the SSL certificate for partnerapi.acme.com is still valid — I want to make sure it hasn't expired before we rely on it in production.”
Investigate HTTPS error on customer-reported site
“A customer is getting a security warning on checkout.shopexample.com — can you pull the TLS certificate summary and tell me if it's expired or unauthorized?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/tls-https?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, structured pass/fail verdict on whether a host's TLS certificate is valid and authorized, especially in automated pre-deployment checks, security monitoring pipelines, or partner API health verification. Prefer the sandbox endpoint (/v1/sandbox/tls-https) for testing before paying $0.006 USDC per call.
Side effects
- Host unreachable or no TLS listener on port 443 — connection timeout or refused error
- Invalid or malformed URL/hostname input — validation error returned
- Certificate exists but is self-signed or from an untrusted CA — ok_check false
- Certificate has expired — ok_check false
- DNS resolution failure for the provided hostname
- Payment failure via x402 protocol — 402 response with payment details
