Restful API /disk/ extra options

I want to attach pools to the restful API request for /disk, but I’m not exactly sure what the format should be. The only hints from the documentation is

include_expired: true - will also include expired disks (default: false)
passwords: true - will not hide KMIP password for the disks (default: false)
pools: true - will join pool name for each disk (default: false)

I’ve made no headway on this. If I attach ?pools=true it doesn’t work.
