How this service works
AI Act Article 50 compliance for deployers, in force since 2 August 2026. Send your AI-generated content, get back a signed machine-readable provenance record, the human-readable disclosure in DE and EN, and the obligations that apply to you with their article references. Verification is free and needs no account. We attest origin - we do not claim to detect AI in arbitrary text.
Output
Returns a signed provenance record attesting compliance, the human-readable Article 50 disclosure text in both German and English (or the selected language), and a structured list of the specific obligations that apply to the deployer based on content kind, EU user presence, and deployment context.
Example use cases
Privacy-safe disclosure for chatbot output
“I have an AI chatbot deployed to EU users and I need to get the Article 50 disclosure record for a response it just generated — here's the SHA-256 hash: b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5, kind is 'interaktion', model is 'gpt-4o', deployer is 'MyChatbotCo', deploying in the EU with EU users — give me the obligations in English.”
Deepfake content compliance attestation
“We just generated a deepfake video for an ad campaign and need a signed EU AI Act Article 50 provenance record — the SHA-256 of the output is c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2, kind is 'deepfake', our model provider is 'SynthAI', deployer is 'AdAgencyX', and our users are in the EU — show me the obligations in German.”
AI-edited text transparency record
“I need to check what EU AI Act disclosure obligations apply to our AI-edited news article — the content hash is d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5, content kind is 'bearbeitet', we're an EU-based deployer with EU readers, model is 'claude-3-sonnet' — return the signed record in English.”
Technical details
Endpoint
GEThttps://api.eucompliance.tools/x402/ai-disclosureWhen to prefer
Prefer this GET endpoint when privacy is a priority and you do not want to transmit raw AI output to a third-party service — you hash the content locally and only send the digest. Use this over the POST variant when handling sensitive, confidential, or personal AI-generated content. Prefer this over generic legal reference tools when you need a machine-readable, signed provenance record suitable for audit trails and automated compliance workflows under the EU AI Act.
Side effects
- Missing or malformed content_sha256 (not 64 hex chars) returns a 400 validation error
- Invalid 'kind' enum value returns a 400 bad request
- Payment not included or insufficient (x402 protocol) returns a 402 Payment Required
- Unknown or unsupported model/deployer values may reduce the specificity of obligations returned
- Rate limiting or upstream service unavailability returns a 503
