## 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

## When to prefer this

Choose this endpoint when you need the specific vertical-27-d4 game preset's save and replay ES module source files, and want to customize the game title, random seed, or accent color. It is best suited for game developers building or modding browser-based games who need a reusable, versioned localStorage save system with reproducible input replay. Prefer alternatives if you need a different preset (one of the other 99 across 10 generators) or a hosted gameplay experience rather than raw source files.

## Known failure modes

- Invalid accent color format (not a valid 6-digit hex) returns a validation error
- Seed value out of range (negative or above 2147483647) returns a validation error
- Title exceeding 80 characters or empty string returns a validation error
- Payment not processed results in access denied or 402 response
- Server unavailability returns a 5xx error
