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 set of URLs for the newly created canvas: an editing URL (for human editing in a browser), a manifest URL, a full-spec URL, a guide URL, and an interactive-view URL. The canvas may be pre-loaded with base64 RGBA pixel data if provided, and includes any game metadata like clips, pivots, and hitboxes configured in the request.

Example use cases

Initialize animated game sprite sheet

“I need a 64x64 pixel canvas for a top-down RPG enemy with four animation clips: 'idle' for frames 0-2, 'attack' for frames 3-6, 'hurt' for frames 7-8, and 'death' for frames 9-12, all at 10 fps.”

Publish pixel art quickly online

“Create a new 128x128 pixel canvas and give me a URL I can share with my team so they can edit and view the sprite in real time without needing any special software installed.”

Preload existing pixel data canvas

“I have base64 encoded RGBA pixel data for a 48x48 character sprite with hitboxes at different animation frames—set up a new canvas with that data pre-loaded and give me the interactive view URL so I can test it in the browser immediately.”

When to prefer

Use this endpoint when you need to programmatically create a new pixel art canvas, especially for game development workflows requiring sprite sheets with named animation clips, per-frame hitboxes, pivot points, and facing metadata. It is ideal when the agent needs to both initialize a canvas and optionally pre-populate it with pixel data in a single call, and when a hosted editing + interactive-view URL is needed for human review or downstream game engine consumption.

Side effects

Invalid or malformed base64 RGBA pixel data returns a 400 error
FPS value outside 1-60 range causes a validation error
More than 64 named animation clips or hitbox items per frame triggers a schema violation
Payment of $0.01 USDC not provided or rejected returns a 402 Payment Required
Canvas dimensions not specified or invalid may return a 400 error
Animation clip frame indices referencing non-existent frames may be rejected
