## 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-starter-open-27-d2-5597faa5 -d '<json body>'
```

Example prompt: Generate me a native WebGPU maze game starter using the open-27-d2 preset, call it 'Dungeon Crawler', use seed 1337, and set the accent color to #ff6a00.

## When to prefer this

Choose this endpoint when you need a ready-to-edit, native WebGPU maze game starter using WGSL shaders and vertex buffers — specifically the open-27-d2 preset. Prefer this over Three.js or other WebGL-based starters when you want low-level GPU API access without abstraction layers. Best for developers who want source-level control over the render pipeline and shader code.

## Known failure modes

- Invalid accent color format (not a valid #RRGGBB hex) returns a validation error
- Title exceeding 80 characters or empty string is rejected
- Seed value outside 0–2147483647 range is rejected
- Payment failure (insufficient USDC balance) prevents file delivery
- Non-WebGPU browser environments cannot run the generated output
