## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability native-webgpu-maze-game-starter-horizontal-27-d4-3353b0fe -d '<json body>'
```

Example prompt: Generate me the horizontal-27-d4 WebGPU maze game starter with the title 'Dungeon Run', seed 1234, and accent color #ff6a00 — I want the editable source files with the WGSL shader and render pipeline.

## When to prefer this

Choose this endpoint when you specifically need the horizontal-27-d4 preset of a native WebGPU maze game starter with WGSL shader source. It is ideal for developers who want a ready-to-edit, GPU-native maze game template without building the render pipeline from scratch. Prefer this over generic game templates when you need WebGPU-specific vertex buffer and WGSL shader code that runs directly in modern browsers.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns validation error
- Seed out of range (negative or above 2147483647) returns validation error
- Title exceeding 80 characters or empty string returns validation error
- Payment not processed or insufficient USDC balance returns 402 error
- WebGPU-incompatible browser cannot run the delivered source files (runtime issue, not API failure)
