Built on the open C2PA standard · EU AI Act ready

Prove what's real.
Sign & verify content provenance.

A dead-simple REST API to embed and read C2PA Content Credentials — cryptographic proof of who made an asset, whether it's AI-generated, and how it was edited.

Two endpoints. That's it.

POST /v1/sign

Embed tamper-evident Content Credentials: creator, AI-or-human origin, edit actions, and any custom claims. Returns a signed download URL.

POST /v1/verify

Read and validate credentials on any asset. Get a clean JSON report: signature issuer, AI flag, authors, actions, and validation status.
