Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-11-d4-5ef863e8 -d '<json body>'
```

Example prompt: Give me the open-11-d4 native WebGPU maze game starter files with the title 'Labyrinth Run', seed 1234, and accent color #ff5500.

## When to prefer this

Choose this endpoint when you specifically need source files for the open-11-d4 preset native WebGPU maze game with WGSL shaders and a vertex buffer render pipeline. Prefer this over Three.js or other WebGL variants when you want low-level GPU access with no third-party rendering library dependency. It is ideal when you want a reproducible, configurable maze starter (by seed, title, accent) for hackathons, game jams, or educational demos.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns validation error
- Seed out of range (negative or above 2147483647) returns schema error
- Missing required payment header returns 402 Payment Required
- Title exceeding 80 characters or empty string returns validation error
- WebGPU output requires a WebGPU-capable browser on HTTPS or localhost to run — no runtime error from API but files won't execute otherwise

## How this service works
