## 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-d2-9d2f1028 -d '<json body>'
```

Example prompt: Generate the horizontal-19-d2 WebGPU maze game starter for me with the title 'Dungeon Escape', seed 1234, and accent color #ff5500 — 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-run, editable WebGPU maze game source with native vertex buffers and WGSL shaders in the horizontal-19-d2 preset layout. It is distinct from generic game templates because it targets the native WebGPU API specifically (not WebGL or Canvas), and delivers source files rather than hosted gameplay, making it ideal for developers who want to customize or embed the game in their own projects.

## Known failure modes

- Invalid accent color format (not matching ^#[0-9a-fA-F]{6}$) returns a validation error
- Seed value outside 0–2147483647 range rejected
- Title exceeding 80 characters or empty string rejected
- Payment not processed (x402 protocol failure) results in no file delivery
- WebGPU-incompatible environment noted in documentation but not enforced server-side
