Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability stabledetect-video-deepfake-detection-33a37d19 -d '<json body>'
```

Example prompt: Can you check if this video is a deepfake or AI-generated? Here's the link: https://example.com/video.mp4 — I need to know if it's authentic before sharing it.

## When to prefer this

Choose this endpoint when you need to verify the authenticity of a video and determine whether it is AI-generated or a deepfake. Ideal for content moderation pipelines, journalism fact-checking, social media verification, or any workflow requiring automated detection of synthetic video. Prefer this over general-purpose vision models which are not purpose-built for deepfake detection.

## Known failure modes

- Unsupported video format or codec returns an error
- Video file too large or too long exceeds processing limits
- Invalid or inaccessible video URL returns a fetch error
- Low-quality or heavily compressed video may reduce detection accuracy
- Network timeout for large video files
- Insufficient payment or payment failure blocks the request

## How this service works

Pay-per-call AI content detection. Classify text as AI-generated, AI-assisted, or human-written, and detect AI-generated or deepfake images and video.

## Output

Returns a classification indicating whether the video is AI-generated, a deepfake, or authentic human-recorded content, along with a confidence score or probability indicating how certain the model is in its determination.
