Verify the C2PA Content Credentials (provenance) of a local image, video, audio, or PDF file. Returns a plain-language verdict (trusted / valid_untrusted / invalid / no_credentials), the signer, whether the content is AI-generated, its edit history, provenance lineage, and any validation issues. Use this when you have a file path on disk. The file is read locally and never uploaded.

Download a remote image, video, audio, or PDF over https and verify its C2PA Content Credentials. Returns the same plain-language verdict, signer, AI-generation status, lineage, and issues as verify_c2pa_file. Use this for a web URL. Only public https URLs are allowed (private/internal hosts are refused).

Audit a folder of media files: report which ones carry C2PA Content Credentials, their verdict, signer, and whether each is AI-generated. Non-recursive. Use this to triage a directory of images/videos at once.

Report the verification engine version, the media types this server can verify, and the active trust-list configuration. Use this to check capabilities before verifying.
