In the API
Send markets=kr on each call to POST /v1/mark: a call that lacks what South Korea's rules need is refused before anything is counted, and each mark gets a receipt of what it carries for each law.
| 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: South Korea's deep fakes in sound need a notice people can hear, which we don't add yet. |
