## 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-vertical-19-d4-14ce1585 -d '<json body>'
```

Example prompt: Give me the native WebGPU maze game starter files for the vertical-19-d4 preset, with the title 'Labyrinth Run', seed 1234, and accent color #ff6a00.

## When to prefer this

Choose this endpoint when you specifically need a native WebGPU (non-framework) maze game starter that uses raw WGSL shaders and vertex buffers, and want the vertical-19-d4 preset layout. Prefer it over the Three.js WebGPU variant when you want no rendering framework overhead and direct GPU pipeline control. Use it when you need editable, configurable source files rather than a hosted playable game.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Title exceeding 80 characters is rejected
- Seed value outside 0–2147483647 range is rejected
- Running the output in a non-WebGPU browser will cause runtime failure (not an API error but a deployment concern)
- Payment failure via x402 protocol results in 402 response and no file delivery
