SSL Certificate Examples
Worked examples for the SSL lookup: the certificate a host serves right now. First valid certificates (on a domain, on an IP address, on another port, with an elliptic-curve key), then certificates with problems, then connections that fail.
The problem certificates come from a public test site that serves broken certificates on purpose. Every example is a real response from September 24, 2026.
To judge a certificate, read parsed.signature.valid and parsed.signature.invalid_reason (why it is not valid), parsed.has_expired and parsed.signature.self_signed. A connection problem is not an HTTP error: the API returns 200 with the reason in connection_status and parsed set to null.
