How it works

Connect your pipeline

One API call where your content is generated. An afternoon, not a quarter.

Every output carries its mark

A C2PA manifest travels invisibly inside the content and survives copy-paste.

See your coverage

Your dashboard shows what share of outputs are marked, ready to show an auditor.

A real signed response in the Encypher dashboard API playground: success true, document ID, and the signed text returned by POST /sign — A real response from the API playground: every output comes back with a verifiable document ID and signed text.

Security and data handling

Standard manifests, no lock-in

Marks are C2PA manifests. Regulators, platforms, and standards-based verifiers can read them without Encypher in the loop.

Audit trail for your evidence file

Every marked output is logged; coverage reporting and a compliance dossier are built into the dashboard.
