Sign and validate C2PA / Content Credentials on every AI-generated image, video and audio file — and get the audit trail you can hand a regulator. One API call.
A $99/mo subscription is cheaper than a €15M fine. No spam — one email when the beta opens.
You keep your workflow. We handle the cryptography, the disclaimers, and the paper trail.
POST an image or video. Get it back with an embedded C2PA manifest and a visible “AI-generated” disclaimer — batch or one at a time.
POST any asset to read its Content Credentials: what made it, when, and whether the mark is intact and trusted.
A dashboard shows your coverage; export a signed audit report that demonstrates Article 50 compliance to a regulator.
The open-source C2PA tools are free — and raw. We wrap them in the API, the batch pipeline, and the audit report your compliance team actually needs.
