## 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-19-d1-b71cd0c6 -d '<json body>'
```

Example prompt: Generate me the horizontal-19-d1 WebGPU maze game starter with the title 'Labyrinth Run', seed 1024, and accent color #ff6600 — I want the editable source files I can run locally on HTTPS.

## When to prefer this

Choose this endpoint when you need ready-to-run, editable maze game source files built on native WebGPU with WGSL shaders — specifically the horizontal-19-d1 preset layout. Ideal for developers who want a low-cost ($0.01 USDC) starting point for a WebGPU game project without writing boilerplate vertex buffers and render pipelines from scratch. Prefer this over generic game templates when you specifically need WebGPU/WGSL code rather than Canvas2D, Three.js, or Unity output.

## Known failure modes

- Invalid accent color format (not a valid #RRGGBB hex string) causes validation error
- Title exceeding 80 characters or being empty is rejected
- Seed value outside 0–2147483647 range is rejected
- Endpoint requires payment of 0.01 USDC via x402 protocol; missing payment results in 402 response
- WebGPU output will not run in non-WebGPU browsers or on non-HTTPS origins
