## 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-d4-c9a7004c -d '<json body>'
```

Example prompt: Generate a native WebGPU maze game starter using the vertical-27-d4 preset — title it 'Crystal Maze', use seed 27, and set the accent color to #ff5577, then give me the source files.

## When to prefer this

Choose this endpoint when you need a native WebGPU game starter (not Three.js) that uses raw WGSL shaders, a vertex buffer, and a render pipeline directly — ideal for developers who want low-level WebGPU control. Prefer this over Three.js WebGPU variants when you want no framework abstraction. The vertical-27-d4 preset is one of 100 available; choose it specifically when you want its unique maze topology configuration.

## Known failure modes

- Invalid accent color format (not a 6-digit hex) returns a validation error
- Seed outside range 0–2147483647 returns an error
- Title exceeding 80 characters is rejected
- Payment failure (insufficient USDC or x402 protocol error) blocks file delivery
- Non-WebGPU browser environment will not run the output files (runtime, not API, failure)

## How this service works

Native WebGPU playable starter: vertical-27-d4: Editable maze game with a native WebGPU vertex buffer, render pipeline and WGSL shader. Requires a WebGPU browser/GPU on HTTPS or localhost. Preset vertical-27-d4; configurable title, seed and accent. Source files, not hosted gameplay. One of 100 presets across 10 shared generators. 0.01 USDC includes one editable playable maze starter.

## Output

Returns native WebGPU source files for the vertical-27-d4 maze game preset, including a vertex buffer definition, WGSL shader code, and render pipeline setup. Files are editable and runnable in a WebGPU-capable browser over HTTPS or localhost. The maze layout and visual accent are parameterized by the supplied seed, title, and accent color.
