In the API
Send markets=us-wa on each call to POST /v1/mark: a call that lacks what the United States' rules need is refused before anything is counted, and each mark gets a receipt of what it carries for each law. The call must also send provider, app_name and app_version.
| 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. |
