Manage the complete lifecycle of verifiable credentials for your digital product passports using a standardized RESTful API specification. Issue, hold, present, exchange, and verify product passport credentials through a consistent OpenAPI 3.0 interface that works across different systems and vendors. vcalm integrates with SSI-HUB for DID management, works with Switchboard for access-controlled credential operations, and can be used alongside Battery Passport VC Schema for structured credential issuance. All credential operations use encrypted communications and cryptographically signed credentials. Support interoperability testing between issuers, holders, and verifiers in your product passport ecosystem. Leverage W3C Credentials Community Group standards to ensure your credential management operations are compatible with industry best practices. Reduce integration complexity with a well-defined API that handles credential lifecycle operations from creation through verification to revocation.
