## 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-d2-4dd43480 -d '<json body>'
```

Example prompt: Generate me the open-19-d2 WebGPU maze game starter called 'Desert Run' with seed 1234 and accent color #ff8844 — I want the editable source files with the WGSL shader and render pipeline.

## When to prefer this

Choose this endpoint when you need editable, ready-to-run WebGPU maze game source code specifically using native vertex buffers and WGSL shaders (preset open-19-d2), rather than Canvas 2D alternatives. Prefer it when you want a low-cost ($0.01 USDC) scaffolded starting point for a WebGPU browser game with custom title, seed, and branding color, rather than a hosted gameplay experience.

## Known failure modes

- Invalid accent color (not a valid 6-digit hex) returns a validation error
- Seed out of range (above 2147483647 or negative) causes a schema error
- Missing or empty title (less than 1 character) fails validation
- Payment failure or insufficient USDC balance prevents generation
- Non-WebGPU browser environment will fail to run the returned source files at runtime
