## 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-19-d1-9682bbd8 -d '<json body>'
```

Example prompt: Generate a WebGPU maze game starter using preset vertical-19-d1 with the title 'Labyrinth Run', seed 77, and accent color #ff6a00 — I want the editable source files I can run locally.

## When to prefer this

Choose this endpoint when you need a ready-to-edit, native WebGPU maze game scaffold with a specific preset (vertical-19-d1), configurable seed, title, and accent color. Prefer it over generic game template services when you specifically require WGSL shader source and a WebGPU render pipeline rather than Canvas2D or WebGL. Ideal for rapid prototyping, game jams, or educational WebGPU demonstrations.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Seed out of range (negative or above 2147483647) causes a parameter error
- Empty or overly long title (>80 chars) triggers a validation failure
- Payment not completed or incorrect USDC amount results in a 402 payment required error
- Server-side generation failure may return a 5xx error with no files
