# Rengi Forge: Level Design – Zone Placement & Preview

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

Generates placements for every zone in a game level, returns previews and a 3D viewer link for the dressed level layout.

## 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-level-design-zone-placement-preview-41e4e9fa -d '<json body>'
```

Example prompt: Can you dress my platformer level — I have three zones (spawn, combat, boss arena) — and generate placements for each zone with previews and a 3D viewer link I can share with my team?

## When to prefer this

Choose this endpoint when you need automated zone-by-zone placement generation for a game level along with visual previews and a 3D viewer link — especially useful for rapid prototyping, game jams, or when you want to iterate on level dressing without manually placing every object. It is purpose-built for game level design workflows, not general 3D scene composition.

## Known failure modes

- Invalid or missing zone/level body data returns a 400 error
- Malformed bodyType (not json/form-data/text) causes request rejection
- Level configuration exceeding service limits may return an error or partial results
- Network or payment failure (x402) results in a 402 or 5xx response with no output

## How this service works

Level design: Dress a level: placements for every zone, previews and a 3D viewer link. Full schema: https://rengi.dev/v1/level-design/schema

## Output

Returns structured placement data for every zone in the level (positions, rotations, asset references), image previews of the dressed level, and a shareable 3D viewer link — conforming to the full level-design schema at rengi.dev/v1/level-design/schema.
