## 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-open-15-d4-54f1290f -d '<json body>'
```

Example prompt: Give me the open-15-d4 Canvas 2D maze game starter with the title 'Labyrinth Run', seed 1337, and accent color #ff6633 — I want the editable source files I can drop straight into my project.

## When to prefer this

Choose this endpoint when you need a self-contained, no-external-library browser maze game starter based on the open-15-d4 preset that you can edit directly. Prefer it over generic game generators when you specifically want Canvas 2D source files with configurable seed, title, and accent color, and don't need a hosted or playable URL — just editable code.

## Known failure modes

- Invalid accent color format (not a 6-digit hex) returns a validation error
- Title exceeding 80 characters is rejected
- Seed outside 0–2147483647 range is rejected
- Payment of 0.01 USDC via x402 not completed results in 402 response
- Server unavailability returns a 5xx error
