अग्रणी कंपनियों का भरोसा
Never let a certificate expire in production again. One call inspects the security certificate of any host and returns everything a monitoring pipeline needs.
Ideal for certificate expiry monitoring and renewal alerts, post-deploy checks in delivery pipelines, and auditing issuers across a domain portfolio. Expired or invalid certificates are still returned in full so you can diagnose them.
The endpoint returns detailed information about a host's security certificate, including the issuer, subject, validity window, days remaining, expiry flags, alternative names, serial number, fingerprint, negotiated protocol, and the full certificate chain.
Key fields in the response include "host," "authorized," "valid_from," "valid_to," "days_remaining," "expired," "not_yet_valid," "serial_number," "fingerprint_sha256," and "subject_alt_names," providing comprehensive certificate details.
The response data is structured in JSON format, with key-value pairs representing various attributes of the security certificate. This allows for easy parsing and integration into monitoring systems.
The endpoint provides information on certificate validity, trust verification, detailed certificate attributes, and handshake protocol details, making it suitable for monitoring and auditing purposes.
Typical use cases include monitoring certificate expiry, setting up renewal alerts, conducting post-deployment checks in CI/CD pipelines, and auditing certificates across multiple domains for compliance.
Users can customize requests by specifying the host they want to inspect in the endpoint URL. This allows for targeted checks on specific domains or services.
Data accuracy is maintained through regular updates and checks against trusted certificate authorities, ensuring that the information returned reflects the current status of the security certificates.
