## 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-15-d4-0a0413c4 -d '<json body>'
```

Example prompt: Generate a WebGPU maze game starter using the horizontal-15-d4 preset, with the title 'Maze Quest', seed 42, and accent color #55b7ff — 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-edit WebGPU maze game starter specifically for the horizontal-15-d4 horizontal preset, with native WGSL shader and render pipeline, and want to customize the maze seed, display title, and accent color. Prefer it over generic game template services when you specifically need WebGPU (not WebGL or Canvas2D) source files that run on HTTPS or localhost without a hosted backend.

## Known failure modes

- Invalid seed value outside 0–2147483647 range returns a validation error
- Accent color not matching ^#[0-9a-fA-F]{6}$ pattern causes request rejection
- Title exceeding 80 characters or being empty causes validation failure
- WebGPU browser requirement not met by end user (client-side, not API failure)
- Payment of 0.01 USDC not processed results in 402 Payment Required response
