## 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-horizontal-15-d2-544b00e8 -d '<json body>'
```

Example prompt: Generate a WebGPU maze game starter using preset horizontal-15-d2, with the title 'Labyrinth Run', seed 123, and accent color #ff6633 — I want the WGSL shader source files I can edit and run locally.

## When to prefer this

Choose this endpoint when you specifically need native WebGPU maze game source files (not a hosted game or a non-WebGPU renderer) using the horizontal-15-d2 horizontal preset. Ideal for developers who want a low-cost ($0.01 USDC), ready-to-edit starting point with WGSL shaders and full control over title, randomization seed, and visual accent color. Prefer this over other presets when the horizontal-15 layout and depth-2 configuration matches your desired maze topology.

## Known failure modes

- Invalid accent color format (must be 6-digit hex) returns validation error
- Title exceeding 80 characters or empty string rejected
- Seed outside 0–2147483647 range returns schema error
- Payment failure or missing x402 payment header results in 402 response
- WebGPU environment incompatibility not detectable at generation time — files may not run if browser lacks WebGPU support
