How this service works
For a domain's current certificate (taken from public Certificate Transparency data via CertSpotter): reads its CRL Distribution Point, downloads that public CRL, and reports whether the certificate's serial number is on it, plus the CRL's thisUpdate and nextUpdate. OCSP is not queried. Revocation status is as of the CRL's publication time.
Output
Returns whether the domain's current TLS certificate serial number appears on the certificate's CRL Distribution Point list, along with the CRL's thisUpdate (last published time) and nextUpdate (next scheduled refresh time). Revocation status reflects the CRL publication time, not real-time OCSP status.
Example use cases
Pre-deployment certificate health check
“Before we push to production, can you verify that the TLS certificate for api.mycompany.com hasn't been revoked according to its CRL distribution point?”
Security audit of third-party vendor
“We're onboarding a new payment vendor — can you check if the certificate for checkout.vendorportal.com is showing as revoked on its CRL, and tell me when that CRL was last published?”
Incident triage for suspicious domain
“We flagged suspicious traffic to login.suspectsite.net — can you check whether their TLS certificate has been revoked via its CRL distribution point and give me the revocation details?”
Technical details
Endpoint
GEThttps://api.webintel-api.workers.dev/api/security/cert-revocation-crl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need CRL-based revocation checking specifically (not OCSP), when you want to inspect the published CRL timestamps, or when OCSP is unavailable or untrusted. Prefer over manual lookups when automating certificate health checks across many domains. Not suitable when real-time OCSP stapling status is required.
Side effects
- Domain has no resolvable certificate in Certificate Transparency logs
- Certificate lacks a CRL Distribution Point extension
- CRL file is unreachable or returns a non-200 response
- Domain parameter missing or malformed
- CRL parsing error due to unexpected format
- Certificate Transparency data may lag real-time certificate issuance
