Sideload Avatar Generator
Generate 3D avatars from text prompts or reference images using Sideload.gg. Pay-per-use via the x402 protocol — $2 USDC per generation on Base.
Works with any x402 wallet. Bring your own wallet and private key — no proprietary wallet required.
What You Get
Each generation produces four formats:
| Format | File | Use Case |
|---|
| GLB | .glb | Universal 3D — Three.js, Unity, Unreal, web viewers |
| VRM | .vrm | Avatar standard — VRChat, VTubing, social apps |
| MML | URL | Metaverse Markup Language — for MML-compatible worlds |
| PNG | .png | Processed reference image used for generation |
🎭 Rendering Avatars with @pixiv/three-vrm
The VRM output is designed to work with @pixiv/three-vrm — the standard Three.js library for loading, displaying, and animating VRM avatars. If you're already building with Three.js, generated avatars plug right in with full skeleton support:
import * as THREE from 'three';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader';
import { VRMLoaderPlugin } from '@pixiv/three-vrm';
const loader = new GLTFLoader();
loader.register((parser) => new VRMLoaderPlugin(parser));
loader.load('https://aiml.sideload.gg/models/avt-xxx.vrm', (gltf) => {
const vrm = gltf.userData.vrm;
scene.add(vrm.scene);
});
This makes it easy to generate an avatar with Sideload and immediately use it in any Three.js scene — games, social apps, virtual worlds, VTubing, and more.

Prerequisites
-
Node.js 18+
-
An x402 payment token — sign a payment with your own wallet/signer and pass it via --x402-token. This skill never handles private keys.
node scripts/generate.js --probe
node scripts/generate.js --prompt "..." --x402-token <base64-encoded-payment>
Use any x402-compatible client to obtain a payment token: Coinbase x402 SDK, Thirdweb x402, or your own signing flow.
Setup
npm install
