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 halowerk-ffmpeg-trim-plan-snapshot-compare-a482a98f -d '<json body>'
```

Example prompt: Compare the video frames at 00:01:15 and 00:02:45 in this clip — https://cdn.example.com/myvideo.mp4 — and tell me how visually different they are so I can decide if that's a good trim point.

## When to prefer this

Choose this endpoint when you need frame-level visual comparison at specific timestamps within a video file, particularly as part of a trim planning or video editing workflow. It is purpose-built for comparing two snapshot moments to support cut decisions, unlike general video analysis tools that operate on entire streams or transcripts.

## Known failure modes

- Video URL is inaccessible or requires authentication — returns fetch error
- Timestamp out of bounds — returns error if timestamp exceeds video duration
- Unsupported video format — ffmpeg may reject certain codecs
- Payment not received via x402 — returns 402 Payment Required
- Malformed request body — returns 400 with validation error
- Server-side ffmpeg processing timeout on large or high-resolution files

## Output

A JSON object containing a visual similarity or difference score between the two extracted video frame snapshots, along with metadata about each snapshot (timestamp, dimensions, etc.) and an assessment of whether the frames differ significantly — useful for automated trim planning and cut-point validation.
