Characters
Create game-ready characters from a text prompt or your own uploaded art.
Generate game-ready sprite sheets from code
Create characters, poses, animations, and sprite sheets with a simple REST API. Send an image or prompt, choose an animation, and get back export-ready assets for your game.
Works with cURL, Python, Node, Unity, Godot, Phaser, and custom game tools.
Quickstart
Grab a key, install nothing, and make your first request.
curl -X POST https://www.autosprite.io/api/v1/characters \
-H "x-api-key: vspk_your_key_here" \
-H "Content-Type: application/json" \
-d '{"name": "Knight", "prompt": "knight with a blue cape, pixel art"}'Build anything 2D
Animations & sprite sheets
Generate idle, walk, run, attack and custom animations, then export PNG sheets + atlases.
Assets
Build standalone game assets — props, items, and effects — then generate previews and even 3D models from them.
Core endpoints
The endpoints below cover the full generation workflow. Complete reference in the API docs.
/api/v1/charactersCreate a character from a text prompt or uploaded image.
/api/v1/characters/{id}/spritesheetsGenerate animations for a character and export the sprite sheet.
/api/v1/characters/{id}/posesGenerate custom poses to use as first or last animation frames.
/api/v1/jobs/{id}Poll the status of a generation job and collect results.
/api/v1/accountCheck your current credit balance.
API access is included with subscription plans.
Frequently asked questions
Is the AutoSprite API free?
API access is included with a subscription plan. Generation endpoints (create character, generate animations) require an active subscription.
What can I build with it?
Create characters from prompts or images, generate animated sprite sheets and custom poses, build game assets, and automate batch pipelines — all over HTTPS.
Which languages are supported?
Any language that can make an HTTPS request: Python, Node.js, Go, Rust, C#, or plain curl. There is no SDK to install.
How is the REST API different from MCP?
MCP connects AutoSprite to AI coding assistants like Claude Code and Cursor. The REST API is for programmatic pipelines and backends. Both are authenticated with the same key.
