## 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-horizontal-19-d4-b4a5f258 -d '<json body>'
```

Example prompt: Generate the horizontal-19-d4 pathfinding ES module with seed 42, title 'Dungeon Run', and accent color #55b7ff — I need the solved routes and source files for my grid game.

## When to prefer this

Choose this endpoint when you need a ready-made, deterministic BFS pathfinding ES module for a specific preset grid layout (horizontal-19-d4) with pre-solved routes, rather than implementing pathfinding from scratch or needing a fully hosted game.

## Known failure modes

- Invalid seed value outside 0–2147483647 range returns validation error
- Title exceeding 80 characters or empty string rejected
- Malformed accent hex color (not matching #RRGGBB pattern) causes validation failure
- Payment of 0.01 USDC not processed results in 402 Payment Required
- Network timeout for POST request

## How this service works

Grid pathfinding module: horizontal-19-d4: Reusable four-neighbour breadth-first shortest-path ES module, preset map and solved exit/collectible routes. Preset horizontal-19-d4; configurable title, seed and accent. Source files, not hosted gameplay. One of 100 presets across 10 shared generators. 0.01 USDC includes one editable game module or map bundle.

## Output

Returns an ES module source file implementing four-neighbour breadth-first search on the horizontal-19-d4 preset grid map, including pre-solved shortest paths to exits and collectibles, configurable via title, seed, and accent color.
