## 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-vertical-15-d4-e68ee555 -d '<json body>'
```

Example prompt: Generate the vertical-15-d4 WebGPU maze game starter with the title 'Crystal Labyrinth', seed 12345, and accent color #ff6a00 — I want the editable source files I can run in my browser.

## When to prefer this

Choose this endpoint when you need editable, ready-to-run WebGPU maze game source files using native GPU APIs and WGSL shaders, specifically the vertical-15-d4 preset layout. Prefer this over generic game templates when you need a specific maze shape, reproducible seed, or custom branding, and when you want to learn or extend real WebGPU rendering code rather than using a canvas/WebGL abstraction.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Seed value out of range (above 2147483647 or negative) returns a schema error
- Title exceeding 80 characters or empty string is rejected
- Payment not completed or insufficient USDC balance prevents file delivery
- WebGPU compatibility issues must be handled client-side after file delivery
