How this service works
DDG agent-payable service request
Output
Returns a confirmation response (ok: true) indicating the media asset has been successfully signed with a C2PA cryptographic manifest, embedding provenance and authenticity metadata directly into the audio/video file.
Example use cases
Certify AI-generated video content
“I just generated a video with our AI pipeline and need to sign it with C2PA credentials before publishing, so viewers can verify it's authentic and see where it came from — can you sign it?”
News agency media authentication
“We have a raw interview audio file we recorded in the field and need to attach verifiable C2PA provenance before submitting it to editors — please sign it so it carries a tamper-evident authenticity record.”
Brand content integrity verification
“Our marketing team produced a product video and we want to embed C2PA content credentials so platforms and consumers can cryptographically verify we made it and it hasn't been altered — can you apply the signing?”
Technical details
Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/c2pa/sign-av?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to embed C2PA-standard cryptographic provenance into audio or video files, especially for AI-generated content, journalism, or brand media where tamper-evidence and origin verification are required. Prefer this over generic file storage or metadata tagging services when the goal is interoperable, verifiable content authenticity credentials recognized by the C2PA standard.
