## 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-preset-open-19-d4-5075cf32 -d '<json body>'
```

Example prompt: Generate me the open-19-d4 Canvas 2D maze game starter called 'Dungeon Escape' with seed 1337 and accent color #ff6600 — I want the editable source files I can host myself.

## When to prefer this

Choose this endpoint when you need a self-contained, no-dependency browser maze game as editable source code rather than a hosted game link. It is ideal when you want a specific visual preset (open-19-d4) with deterministic maze generation via seed, custom branding via title and accent color, and full ownership of the source files for modification or self-hosting.

## Known failure modes

- Invalid accent color format (not matching ^#[0-9a-fA-F]{6}$) returns validation error
- Title exceeding 80 characters or empty string rejected
- Seed value out of range 0–2147483647 returns error
- Payment not processed (x402 protocol failure) results in no file delivery
- Network timeout or server error returns 5xx with no source files
