Or I could not be an idiot and tell you the command specifically looking up a key for a file: lookupkey

    ## git annex lookupkey CG\ Cookie/Compositing\ in\ Blender/01_CompositingInBlender_SourceFiles.zip 
    SHA256E-s744506832--08d2daced60b5eb6509044d5eefca82e7a6899350f49adc0083014229739515e.zip

So to get the backend (if the first component is always the backend):

    ## git annex lookupkey CG\ Cookie/Compositing\ in\ Blender/01_CompositingInBlender_SourceFiles.zip | cut -d- -f1
    SHA256E
