No general labelling law found. From 72 h before a vote to 24 h after, TSE rules ban new AI content using candidates' or public figures' image or voice.

Rules for specific sectors

Political ads and campaigns

TSE Resolution 23.610/2019, Art. 9-B (election ads): In force since 4 March 2024. State explicitly and prominently that content was AI-made or altered and which technology was used.

Bills and drafts

Not law: they don't change a country's coverage or what a call needs.

Brazil AI Bill PL 2338/2023: Draft: not in force. An identifier in synthetic content to verify its authenticity or provenance, as set by regulation.

In the API

Send markets=br on each call to POST /v1/mark: a call that lacks what Brazil'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 Brazil carries, by kind of file
File	Made with AI	A deep fake (`deepfake=true`)
Picture	Watermark and Content Credentials	Watermark and Content Credentials
Clip	Watermark and Content Credentials	Watermark and Content Credentials
Song	Watermark and Content Credentials	Refused for now: a song can't carry a visible label, and spoken notices for deep fakes aren't available yet: leave "deepfake" off for songs.
