## 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-23-d4-1e4e3a0e -d '<json body>'
```

Example prompt: Generate me the horizontal-23-d4 WebGPU maze game starter with the title 'Labyrinth Run', seed 1234, and accent color #ff6600 — I want the editable source files I can run on localhost.

## When to prefer this

Choose this endpoint when you need a ready-to-edit, native WebGPU maze game starter using WGSL shaders for the horizontal-23-d4 layout preset, especially when you want a specific reproducible maze via seed and branded colors. Prefer this over generic game templates when you specifically need WebGPU vertex buffer and render pipeline scaffolding for browser-based games.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Seed value out of range (negative or above 2147483647) returns a validation error
- Title exceeding 80 characters or empty string returns a validation error
- Payment failure or insufficient USDC balance prevents file delivery
- WebGPU not supported in the requesting browser environment — client-side limitation not detectable at API level
