## 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-open-27-d3-1e206e1a -d '<json body>'
```

Example prompt: Generate me the open-27-d3 native WebGPU maze game starter with the title 'Crystal Labyrinth', seed 1337, and accent color #ff5500 — I want the editable source files with the WGSL shader and render pipeline included.

## When to prefer this

Choose this endpoint when you need editable, ready-to-run native WebGPU maze game source code with WGSL shaders and a full render pipeline, specifically for the open-27-d3 preset. It is ideal when you want a reproducible maze layout via seed, a custom game title, and a branded accent color. Prefer this over Canvas 2D variants when you specifically require native WebGPU vertex buffer rendering rather than a browser 2D canvas fallback.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Seed value out of range (negative or above 2147483647) causes a parameter rejection
- Title exceeding 80 characters or being empty is rejected
- Missing payment or failed x402 payment results in a 402 Payment Required response
- Calling from a non-HTTPS, non-localhost context may cause browser-level WebGPU unavailability at runtime (not an API error but a downstream failure)
