That's not really API :)
Just create module with base class PVE::Storage::Plugin, add api() 
method and reload methods:

type, plugindata, properties, options, parse_volname, filesystem_path, 
create_base, clone_image, alloc_image, free_image, list_images, status, 
activate_storage, deactivate_storage, activate_volume, 
deactivate_volume, volume_resize, volume_snapshot, 
volume_snapshot_rollback, volume_snapshot_delete, volume_has_feature.

Many of them may be just placeholders, dying with errors or silently 
returning true, if your module not provides some functionality. See 
/usr/share/perl5/PVE/Storage/Plugin.pm for lists of parameters and 
returning values.

Although, simple description of parameters and returning values of these 
methods in comments in Plugin.pm (maybe in POD format?) could be helpful.
