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-maze-game-starter-horizontal-27-d1-a6e2a027 -d '<json body>'
```

Example prompt: Generate a WebGPU maze game starter using the horizontal-27-d1 preset with the title 'Lost Corridors', seed 1337, and accent color #ff5533 — I want the editable source files I can run in my WebGPU-capable browser.

## When to prefer this

Choose this endpoint when you need a ready-to-edit, GPU-native browser maze game scaffold using the WebGPU API with WGSL shaders — specifically the horizontal-27-d1 preset. It is ideal for developers who want a low-cost ($0.01 USDC) starting point for a customizable maze game with deterministic seeding, rather than a fully hosted game or a non-WebGPU canvas-based alternative.

## Known failure modes

- Invalid accent color format (not a 6-digit hex) returns a validation error
- Seed out of range (>2147483647 or <0) returns a validation error
- Title exceeding 80 characters or empty string returns a validation error
- Payment failure (insufficient USDC balance or x402 protocol error) prevents file delivery
- Service unavailable if the upstream market endpoint is down
