## 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-playable-maze-starter-horizontal-19-d4-0bd7b104 -d '<json body>'
```

Example prompt: Give me the horizontal-19-d4 WebGPU maze game starter with the title 'Maze Quest', seed 42, and accent color #55b7ff — I want the editable source files with the WGSL shader and render pipeline.

## When to prefer this

Choose this endpoint when you need a ready-to-edit WebGPU maze game starter specifically using native vertex buffers and WGSL shaders, and want configurable branding (title, seed, accent color) for the horizontal-19-d4 layout preset. Prefer this over generic game template services when targeting WebGPU-native browser environments with a real shader pipeline rather than canvas or WebGL fallbacks.

## Known failure modes

- Invalid accent color format (must be 6-digit hex like #55b7ff) returns a validation error
- Seed out of range (must be 0–2147483647) causes rejection
- Title exceeding 80 characters or being empty fails validation
- Payment failure via x402 protocol prevents file delivery
- WebGPU environment not present at runtime (client-side issue, not API failure)
