## 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 canvas-2d-playable-maze-starter-horizontal-27-d4-6e39719f -d '<json body>'
```

Example prompt: Generate me the horizontal-27-d4 Canvas 2D maze game starter with the title 'Dungeon Escape', seed 123, and accent color #ff6600 — I want the editable source files I can modify myself.

## When to prefer this

Choose this endpoint when you need a ready-to-edit, dependency-free Canvas 2D maze game scaffold with a specific horizontal layout preset (horizontal-27-d4) and want to customize the title, random seed, and accent color. Prefer it over Three.js/WebGL variants when you want pure browser Canvas 2D with no external libraries, and over generic code generators when you need a game-specific, immediately playable maze template.

## Known failure modes

- Invalid accent color format (must be 6-digit hex like #55b7ff) returns validation error
- Seed outside 0–2147483647 range is rejected
- Title exceeding 80 characters or empty string is rejected
- Payment failure or insufficient USDC balance prevents file delivery
