ISCC C2PA Resolver¶

Experimental

This beta MVP and its documentation are provided as is, without warranty of any kind. The API, the gateway contract and the public instances may change in breaking ways before version 1.0.

Recover lost Content Credentials by content¶

A C2PA Manifest gets lost when a platform strips metadata or re-encodes a file. The ISCC C2PA Resolver finds it again: it answers C2PA soft binding queries for the fingerprint algorithm io.iscc.v0 by searching the ISCC Discovery Protocol, and points the client to the manifest.
