Core API

Certificate

Retrieve the issuance certificate for a sealed artifact. Certificates provide an audit trail of how and when an artifact was issued.

GET/v1/certificate/:idscope: verify

Overview

When an artifact is sealed via the Issue endpoint, a certificate record is created containing metadata about the issuance. Use this endpoint to retrieve certificate details for audit, compliance, or verification purposes.

Important: Certificates provide issuance metadata only. They do not constitute legal advice, regulatory approval, or validation of consent quality.

Path Parameters

Parameter	Type	Required	Description
