## 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 grid-pathfinding-module-vertical-19-d4-ae711835 -d '<json body>'
```

Example prompt: Generate me the vertical-19-d4 BFS pathfinding ES module with the title 'Dungeon Run', seed 101, and accent color #ff5533 — I need the pre-solved exit and collectible routes as source files.

## When to prefer this

Choose this endpoint when you need a ready-to-use BFS four-neighbour pathfinding ES module for a vertical maze layout (preset vertical-19-d4) with pre-solved exit and collectible routes, and you want to customise the seed, title, and accent color. Prefer this over generic pathfinding libraries when you want a self-contained, pre-solved preset module rather than a runtime solver, and over other presets when the vertical-19-d4 layout specifically fits your game design.

## Known failure modes

- Invalid seed value (out of 0–2147483647 range) returns validation error
- Invalid accent color format (not matching ^#[0-9a-fA-F]{6}$) returns schema error
- Title exceeding 80 characters or empty string rejected
- Payment failure over x402 protocol prevents module delivery
- Seed produces degenerate or unsolvable map edge case (unlikely but possible with certain values)
