Is there any API for it?

My original need was just add a displayable custom property for tile, also for empty tile. So I make a object layer for it, but the coordinates between them was quit differentce.

You can convert from tile coordinates to pixel coordinates (for positioning objects) using [`tileToPixel`](https://www.mapeditor.org/docs/scripting/classes/TileMap.html#tileToPixel), and the other way around using [`pixelToTile`](https://www.mapeditor.org/docs/scripting/classes/TileMap.html#pixelToTile). Does that help?
