How this service works

Import agent-owned pixel canvases.

Output

Returns a canvas object representing the imported pixel art, including a canvas ID and the initialized canvas state derived from the source image, ready for further editing or export operations.

Example use cases

Game sprite editing setup

“Load my existing game character sprite from https://assets.mygame.com/hero.png into a pixel art canvas on WithZero so I can tweak the colors.”

Pixel art logo retouching

“Import this logo image at https://mybrand.com/logo.png into a pixel art canvas so I can touch it up and export it as pixel art.”

Tileset import for level design

“Bring in my tileset PNG from https://cdn.myproject.io/tileset.png into a pixel art canvas so I can use individual tiles in my level editor.”

When to prefer

Choose this endpoint when you need to bring an existing image or pixel art asset into a WithZero pixel art canvas as a starting point for editing, rather than generating new pixel art from scratch. Prefer this over generation endpoints when the user already has a source image they want to work from.

Side effects

Invalid or unreachable image URL returns an error
Unsupported image format causes import failure
Image too large exceeds canvas size limits
Payment failure (insufficient USDC balance) blocks the call
Rate limiting or service unavailability returns 5xx error
