Untested but this should work:
curl --data 'uuid=["2f53276d5f8dc339751dc54dec52a7c6","4d04dcf36d9dbda5fc7566804e569ba7","b9de98661b0fe72c13c822271a58f8d5","33dfc74ac7cbac60e31b8dfe181ba848","cce069ae2c81dc616a92972c332beee4"]' http://10.0.0.2:9981/api/idnode/delete
Of course if you don't know the UUIDs in advance you would have to find them with api/channeltag/list.
