The Article 50 enforcement pack.

Free Article 50 Passport API + 12-month audit pack + 5 named-franchise templates. The fastest path to defensible compliance.

What's required

Every AI-generated content item must have a machine-readable transparency marker identifying it as AI-generated, plus a watermark for synthetic media. Deployers must make AI-generated content detectable as such to natural persons. Fines: €15M or 3% global turnover (whichever higher).

Who needs it

Anyone deploying AI in the EU 27. Generative AI providers (OpenAI, Anthropic, Google, Mistral, in-house models). Deployers of those models. Distributors. Importers. Sub-150 person orgs (startups) exempt from MOST but not all obligations.

What CSOAI ships

Free Article 50 Passport API (/api/article50): issue HMAC-signed or Ed25519-signed passports per content item. 3 tiers: Free (HMAC, verifiable at proofof.ai), Pro (Ed25519, audit-grade), Governance (Ed25519 + BFT 23/33 + OTS, court-admissible). Free browser UI at /article50.html.

What you ship

A passport per content item. Watermarking at the model layer (C2PA, SynthID, provider-native). Detection at the deployer layer. The passport proves good faith at the time of issuance. Watermarking at retrieval is a separate (C2PA Content Credentials) layer.

The 3 enforcement gaps you can't ignore

1. The 7 May 2026 EU Digital Omnibus Act did NOT delay Article 50

There's a rumour that the Omnibus Act (proposing changes to AI Act timeline) delayed Article 50. It didn't. The Omnibus Act is still in proposal stage — Article 50 enforcement is on track. The European Parliament and Council have not voted to delay. Plan for 2 August 2026.

2. Watermarking ≠ detection

Watermarking (embedding a marker) is the provider's job. Detection (knowing whether content has a marker) is the deployer's job. You need BOTH. The CSOAI passport proves you attempted the watermarking at issuance; detection confirms it survived downstream edits.

3. The passport alone isn't enough — you also need the audit trail

Per Article 12, you need records of compliance. CSOAI's Article 50 Passport is the foundation. The audit pack (PDF + OSCAL JSON) bundles all your passports into a regulator-submittable package.
