How this service works
Create a new pixel art canvas. Returns editing, manifest, full-spec, guide, and interactive-view URLs. Optionally pre-load base64 RGBA pixels. Full agent guide: https://pixelart.withzero.xyz/llms.txt
Output
Returns a JSON object containing: a UUID canvas ID (used in all subsequent draw, fill, shape, and export API calls), the canvas dimensions (width and height), a viewUrl pointing to the interactive live editor pre-loaded with this canvas, an apiUrl as the base for further API operations on this canvas, and an ansiUrl for rendering the canvas as ANSI half-block art in a terminal or agent context.
Example use cases
Initialize sprite sheet for game development
“Set up a 128x128 pixel canvas I can use to create a character sprite sheet with transparency, and give me the live editor link so I can preview while my agent draws the individual sprites programmatically.”
Start animated pixel art sequence
“Create a new 32x32 transparent pixel canvas for an animation loop I'm building — I need the canvas ID to draw each frame and the ANSI terminal view to preview it as I go.”
Build collaborative pixel art grid
“Initialize a 256x256 blank pixel art canvas so my team can contribute sprites and patterns to it via the API — I want the interactive editor URL to review everyone's contributions in real-time.”

Endpoint
POSThttps://pixelart.withzero.xyz/api/v1/canvasWhen to prefer
Use this endpoint as the mandatory first step whenever you need to create a new pixel art canvas from scratch. It is the entry point for the entire pixel art workflow — you must call this before any draw, fill, shape, or export operations. Choose this over the image-to-pixel-art conversion endpoint when you want a blank canvas rather than converting an existing image.
Side effects
- Width or height out of range (must be 8–256): returns 400 with validation error
- initData length mismatch — base64-decoded bytes do not equal width × height × 4: returns 400
- initData is not valid base64: returns 400 with parse error
- Name exceeds 100 characters: returns 400
- Service unavailable or internal error: returns 5xx
