How this service works
Call when an agent needs whether the port-443 certificate stays valid for at least 14 days. The threshold changes the ok_check bit. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/tls-expiry-14 first.
Output
Returns an ok_check boolean (true if the certificate is valid for at least 14 days, false otherwise), along with relevant expiry metadata for the queried host's port-443 TLS certificate.
Example use cases
Pre-deployment certificate health check
“Before we push the release, can you verify that the TLS certificate on api.mycompany.com is valid for at least 14 more days? I don't want an expiry to take down the deployment.”
Monitoring expiring certs in a fleet
“Check whether the SSL certificate on shop.brandname.com is still good for at least two weeks — we need to know if it'll expire before the renewal job runs.”
Third-party vendor cert verification
“We're integrating with a partner API at payments.vendorname.io — can you confirm their port-443 certificate won't expire within the next 14 days before we go live?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/tls-expiry-14?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs a quick, deterministic pass/fail check on whether a specific host's TLS certificate will remain valid for at least 14 days. Ideal for pre-deployment checks, automated certificate monitoring pipelines, and third-party dependency health verification where the 14-day threshold is the relevant boundary.
Side effects
- Host unreachable or DNS resolution failure — endpoint cannot connect to inspect the certificate
- Invalid hostname or URL format — request rejected before network call
- Certificate already expired — ok_check returns false
- Self-signed or untrusted certificate chain — may fail validation checks
- Payment not processed — x402 payment required error blocks response
