## 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-27-d2-bc93f7e3 -d '<json body>'
```

Example prompt: Generate me a WebGPU maze game starter using the vertical-27-d2 preset with the title 'Maze Quest', seed 42, and accent color #55b7ff — I need 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, native WebGPU maze game starter with a specific preset layout (vertical-27-d2), and want to customize the title, seed-based maze generation, and accent color. Ideal for developers who want a low-cost ($0.01 USDC) starting point for a browser-playable maze game using real WGSL shaders and GPU render pipelines, rather than a canvas-based or third-party engine approach.

## Known failure modes

- Invalid accent color format (not matching ^#[0-9a-fA-F]{6}$) returns a validation error
- Title exceeding 80 characters or empty string is rejected
- Seed value outside 0–2147483647 range fails validation
- Payment of 0.01 USDC not completed results in 402 Payment Required
- Browser/GPU not WebGPU-capable means delivered files won't run client-side (not an API error but a runtime limitation)
