- `forge\_help`: What Rengi Forge offers, prices and how payment works. Free.
- `level\_design\_catalog`: Ingest your prop catalog: footprint, height, pivot and category computed from each GLB. Returns a catalogId for place. Price: $0.50 USDC via x402, charged only on success. Part of Level design: Level dressing for 3D games.
- `level\_design\_place`: Dress a level: placements for every zone, previews and a 3D viewer link. Price: $1.00 USDC via x402, charged only on success. Part of Level design: Level dressing for 3D games.
- `level\_design\_revise`: Change a placed level by instruction or structured zone edits: denser or sparser, other assets, remove a kind of prop; untouched zones keep their exact transforms.
