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 rengi-forge-video-to-sprite-sheet-converter-459d825a -d '<json body>'
```

Example prompt: Take this Kling animation video URL and turn it into a sprite sheet at 12 fps with a 256px frame size, remove the background automatically, and give me the TexturePacker JSON and Godot SpriteFrames export.

## When to prefer this

Choose this endpoint when you need to convert an AI-generated animation (from Kling, Veo, Sora, or similar) or a captured GIF/video into a game-ready sprite sheet with professional preprocessing — background removal, jitter-free frame alignment, loop detection, and direct export to TexturePacker or Godot formats — rather than doing raw frame extraction only. It is especially valuable when you need engine-compatible metadata alongside the image.

## Known failure modes

- Video too large or format unsupported — only MP4, WebM, MOV, GIF accepted
- AI background removal limited to 24 frames maximum
- maxFrames or fps combination exceeds limits (max 120 frames, max 60 fps)
- Invalid or unreachable videoUrl returns an error
- Base64-encoded video malformed or exceeds size limits
- frameSize out of range (must be 16–1024)
- Payment not provided or x402 payment fails

## How this service works

Sprite tools: Turn an animation video or GIF (from Kling, Veo, Sora or a capture) into a sprite sheet: frames at your fps, background removed, every frame aligned to one box and pivot so it does not jitter, the best loop point, TexturePacker JSON, Godot SpriteFrames and a GIF preview. Full schema: https://rengi.dev/v1/sprite-tools/schema

## Output

Returns a sprite sheet image with all frames aligned to a consistent bounding box and pivot point (to eliminate jitter), background removed, the optimal loop point identified, a TexturePacker JSON layout, a Godot SpriteFrames file, and an animated GIF preview of the result.
