How to check if image has layers (MagickCore/MagickWand)

[nsh]

I'm trying to find function to just check if image has layers,
(found deprecated function ClipPathImage, but that checks for ClipPaths . . .)

for example, i have a PSD file, and just want to use MagickCore/MagickWand to check if image has layers or not.

what function can i use for that ?
