Get the Mintall Certificate for Product (MC4P) data for an asset.

An authorized asset returns the full document. A not-authorized asset (parent product not active) returns the identity-only document: the mintall:contentCredentials, mintall:nft, verification and proof blocks are omitted, not null.

AssetCertificateResponse

Asset MC4P certificate as a mintall:-namespaced ImageObject.

This is the lossless full expansion of one entry in the product certificate’s mintall:images[] array. It is the image node (merge key contentUrl) rather than a DigitalDocument wrapper, so a crawler can pivot from the on-page summary onto this document without remapping fields.
