routes: 

  devise_for :admin_users, ActiveAdmin::Devise.config
  ActiveAdmin.routes(self)
  mount_devise_token_auth_for 'User', at: 'auth'

controller
class ApiController < ActionController::Base
  include DeviseTokenAuth::Concerns::SetUserByToken
end

class ApplicationController < ActionController::Base
end

module V1
  class mycontrollerController < ActionController::Base
   def create
     User.is_valid_token(token, client_id)
   end
  end
end


model 
class User < ActiveRecord::Base
  # Include default devise modules.
  devise :database_authenticatable, :registerable,
          :recoverable, :rememberable, :trackable, :validatable
          # :confirmable, :omniauthable
  include DeviseTokenAuth::Concerns::User
  def self.is_valid_token(token,client_id)
  	@resource.valid_token?(token, client_id)
  end
end

@blaslaunchlabs I think you need in your controller find a user firstly. As I realized valid_token? is object method and @ resource object is nil. Try something like this in your controller:

 def create
  @user = User.find(client_id)
  @user.valid_token?(token, client_id)
 end

Thanks @dks17 its working that way.
