Create deepfake detection

Analyze audio, image, and video for deepfake detection.

Supply media via one of three intake methods:

• Direct file upload — multipart/form-data with the file attached as file. Files must be 150 MB or smaller and use one of the supported audio/video/image extensions. For larger files, use the secure upload flow.
• Public URL — application/json with a url field. The API fetches the URL itself.
• Secure upload token — application/json with a media_token field obtained from POST /secure_uploads.

Exactly one of file, url, or media_token must be provided per request.

Set detect_watermark=true to run Resemble watermark detection and SynthID alongside the deepfake analysis. This option supports single audio, image, and video requests only. It adds one Watermark detection charge, applies a 200 MB source limit for audio, image, and video, and causes Prefer: wait and callbacks to wait for the watermark analysis to reach a terminal state. A watermark failure is returned in the nested watermark object and does not change the deepfake verdict.
