$ ros2 service list -t
/even_parameters_node/describe_parameters [rcl_interfaces/srv/DescribeParameters]
/even_parameters_node/get_parameter_types [rcl_interfaces/srv/GetParameterTypes]
/even_parameters_node/get_parameters [rcl_interfaces/srv/GetParameters]
/even_parameters_node/list_parameters [rcl_interfaces/srv/ListParameters]
/even_parameters_node/set_parameters [rcl_interfaces/srv/SetParameters] <== You can get type
/even_parameters_node/set_parameters_atomically [rcl_interfaces/srv/SetParametersAtomically]

$ ros2 service call /even_parameters_node/set_parameters rcl_interfaces/srv/SetParameters "{parameters: [{name: use_sim_time, value: {type: 2, integer_value: 2}}]}"
