# Rengi Forge: 2D Tilemap Level Design

> Rengi Forge: 2D Tilemap Level Design is a paid API for AI agents from rengi.dev, paid per call via x402, $1/call, status unknown (last checked 2026-10-22).

Fills a 2D tilemap with terrain (including proper corner transitions), decorations, obstacles, and multi-tile stamps, then outputs Tiled .tmj, Unity Tilemap JSON, and a preview image.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 rengi-forge-2d-tilemap-level-design-6923f30b -d '<json body>'
```

Example prompt: Generate a 2D tilemap level for my platformer — grassy terrain with proper corner transitions, scattered trees and rocks as decorations, some spike obstacles, and a few multi-tile castle stamp structures; give me back the Tiled .tmj file, a Unity Tilemap JSON, and a preview image.

## When to prefer this

Choose this endpoint when you need a complete, game-engine-ready 2D tilemap with terrain corner transitions, decorations, obstacles, and multi-tile stamps in one call — especially when you need simultaneous Tiled .tmj and Unity Tilemap JSON output. Prefer it over manual tile placement tools when automating level generation pipelines for Unity or Tiled-based games.

## Known failure modes

- Invalid or missing required body fields returns a 400-level error
- Tilemap dimensions too large may time out or return an error
- Unsupported stamp or tile type references cause schema validation failures
- Malformed JSON body results in a parse error response
- Payment not completed (x402) results in a 402 Payment Required response before generation begins

## How this service works

Level design: Fill a 2D tilemap: terrain with proper corner transitions, decorations, obstacles and multi-tile stamps; Tiled .tmj, Unity Tilemap JSON and a preview. Full schema: https://rengi.dev/v1/level-design/schema

## Output

Returns a Tiled .tmj file, a Unity Tilemap JSON, and a preview image of the generated level — including terrain tiles with proper corner/edge transitions, placed decoration tiles, obstacle tiles, and any multi-tile stamp objects, all laid out according to the provided level design parameters.
