## 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-playable-maze-starter-open-23-d4-f81c78dd -d '<json body>'
```

Example prompt: Generate a native WebGPU maze game starter for preset open-23-d4 with the title 'Labyrinth Run', seed 1337, and accent color #ff6600 — 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 native WebGPU maze game scaffold with WGSL shaders for a specific preset (open-23-d4), and want to control the seed, title, and accent color. Prefer this over generic code generation when you want a pre-wired render pipeline and vertex buffer setup that works on HTTPS or localhost with a WebGPU-capable browser, saving boilerplate setup time.

## Known failure modes

- Invalid accent color format (not a 6-digit hex) returns a validation error
- Seed value out of range (negative or above 2147483647) causes a rejection
- Title exceeding 80 characters or empty string fails validation
- Network or payment failure returns a 402 or 5xx error
- WebGPU output cannot be rendered in non-WebGPU browsers (runtime environment issue, not an API error)
