## 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 relaystation-video-storyboard-sprite-sheet-generator-15ad8231 -d '<json body>'
```

Example prompt: Can you generate a storyboard sprite sheet from this video — https://example.com/myvideo.mp4 — sampling one frame every 10 seconds so I can use it as a scrubber timeline in my video player?

## When to prefer this

Choose this endpoint when you need a single-call solution to generate a video scrubber sprite sheet or storyboard thumbnail grid from a video URL, especially in a pay-per-call context with x402 micropayment support. Ideal for video player UIs, content review tools, and media libraries that need frame previews without downloading the full video.

## Known failure modes

- Invalid or inaccessible video URL returns an error
- Video format not supported causes processing failure
- Very long videos may time out if frame count is too high
- Rate limiting or payment failure prevents processing
- Unsupported frame sampling parameters return validation errors

## How this service works

$0.0008/call. Frame-sampled thumbnail sprite sheet from a video — scrubbers and previews in one call. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

A sprite sheet image (a grid of video frame thumbnails sampled at regular intervals) returned as an image file or URL, suitable for use as a scrubber timeline or storyboard preview in video players and media tools.
