General rules

EU AI Act, Article 50 (EU): In force since 2 August 2026. Machine-readable, detectable marks on AI output; a clear notice on deepfakes and AI public-interest text.

Rules for specific sectors

Political ads and campaigns

Latvian Pre-election Campaigning Law, Section 3.1: In force since 7 November 2024. Clearly and unambiguously state that an AI-made likeness of a person or an invented event is used.

Platforms

DSA Art. 35(1)(k) (Regulation (EU) 2022/2065) (EU): In force since 25 August 2023. Prominent markings on realistic generated or manipulated images, audio and video shown on their interfaces.

In the API

Send markets=lv on each call to POST /v1/mark: a call that lacks what Latvia's rules need is refused before anything is counted, and each mark gets a receipt of what it carries for each law.

What a mark for Latvia carries, by kind of file
File	Made with AI	A deep fake (`deepfake=true`)
Picture	Watermark and Content Credentials	Watermark, Content Credentials and the visible label
Clip	Watermark and Content Credentials	Watermark, Content Credentials and the visible label
Song	Watermark and Content Credentials	Refused for now: the EU's deep fakes in sound need a spoken notice (Art. 50(4)), which we don't add yet.
