Pixel Art AI Animation Cycle Generator

by pixelart.withzero.xyz·Website ↗API ↗

Pixel Art AI Animation Cycle Generator is a paid API for AI agents from pixelart.withzero.xyz, paid per call via MPP, $0.3/call, status unknown (last checked 2026-10-10, last successful call 2026-07-16).

Uses the Retro Diffusion AI model to generate a game-quality pixel-art animation cycle (4–16 frames) from the current canvas, redrawing the sprite per frame for presets like walking, idle, jump, attack, and more.

How this service works

Generate a flattened animation cycle through Retro Diffusion and atomically replace the canvas frames. This is the legacy external-provider compatibility route; use segmentation plus layer transforms when authored, deterministic motion is required. Full agent guide: https://pixelart.withzero.xyz/llms.txt

Output

Returns a JSON object with the canvas ID, the total frame count after generation, the provider used, and a viewUrl where the animation can be previewed or shared. The animation replaces all existing flat frames on the canvas.

Example use cases

Idle animation for game character

“Generate a 6-frame idle animation for my pixel art sprite using Retro Diffusion — I want subtle breathing and blinking motions to make the character feel alive.”

Attack animation cycle generation

“Create a 10-frame attack animation from my canvas with Retro Diffusion — the character should swing a sword with realistic arm movement and follow-through.”

Jump sequence for platformer game

“Make a 4-frame jump animation cycle for my pixel art character using Retro Diffusion — show the crouch, takeoff, peak, and landing poses smoothly.”

Technical details

Endpoint

POSThttps://pixelart.withzero.xyz/api/v1/canvas/{id}/animate?utm_source=zero.xyz

When to prefer

Use this endpoint when you need AI-generated, game-quality pixel art animation with realistic pose changes per frame (not sliding cutouts). Ideal for game developers who want walking, idle, attack, or custom motion cycles without manually drawing each frame. Choose this over manual frame endpoints when you want Retro Diffusion to handle the per-frame sprite redrawing automatically.

Side effects

Canvas dimensions outside 32–256px per side — returns validation error
Canvas has active layers with cels that override frames — results may be unexpected unless layers are flattened first
custom_action preset used without a prompt field — returns validation error
Timeout if generation takes longer than 120s — may need retry
Invalid canvas ID — returns 404 not found
Invalid frame count (not one of 4,6,8,10,12,16) — returns validation error

Input

Schema · Request body

Field	Type	Description
