## 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-19-d4-8b8e8cbb -d '<json body>'
```

Example prompt: Generate me the open-19-d4 WebGPU maze game starter with the title 'Dungeon Crawler', seed 1337, and accent color #ff6600 — I want the editable source files I can drop into my own project.

## When to prefer this

Choose this endpoint when you need ready-to-run, editable WebGPU maze game source files for a specific preset (open-19-d4) that can be customized with a title, random seed, and accent color. It is ideal for developers who want a native WebGPU + WGSL starting point without building the render pipeline from scratch, and who want a reproducible maze layout via seed.

## 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) returns a parameter error
- Title exceeding 80 characters or empty string returns a validation error
- Payment not processed or insufficient USDC balance results in a 402 error
- WebGPU browser requirement not met at runtime (client-side, not an API error)
