## 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 ddg-c2pa-audio-video-verification-18582712 -d '<json body>'
```

Example prompt: Can you verify the authenticity and C2PA provenance of this video file I'm looking at — I want to know if it's been tampered with or if it has valid content credentials?

## When to prefer this

Choose this endpoint when you need standards-based C2PA content provenance verification for audio or video media, particularly when you need to detect AI-generated content, deepfakes, or unauthorized modifications. Prefer this over generic file analysis tools when C2PA manifest validation and chain-of-custody provenance are specifically required.

## Known failure modes

- Missing or malformed media body in request returns validation error
- Content without embedded C2PA manifest returns unverified status
- Unsupported media format results in processing error
- Network timeout if media file is too large or slow to fetch
- Payment failure via x402 prevents request processing

## How this service works

DDG agent-payable service request

## Output

Returns a verification result indicating whether the audio or video content passes C2PA authenticity checks, including provenance metadata, manifest validity, and whether the content has been altered since signing. The response includes an 'ok' boolean and associated provenance details.
