## 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-27-d4-d8e86713 -d '<json body>'
```

Example prompt: Generate me the open-27-d4 Canvas 2D maze game starter with the title 'Labyrinth Run', seed 1234, and accent color #ff6600 — I want the editable source files I can customize myself.

## When to prefer this

Choose this endpoint when you need a self-contained, no-dependency Canvas 2D maze game starter that is immediately editable in the browser, especially when you want deterministic maze generation via a seed, a specific preset aesthetic (open-27-d4), and full source-level control rather than a hosted or iframe-embedded game.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Title exceeding 80 characters or being empty triggers a schema validation failure
- Seed value outside the 0–2147483647 range is rejected
- Payment failure via x402 protocol prevents file delivery
- Server-side generation error may return a 500 with no files
