This is just pseudo-code to give you a general idea:

# client code
class MyClient
  def get(params)
    RestClient.get '/some/api', params
  end
end

# resource code
allow_filter :name do |scope, val|
  scope.merge!(name: val)
end

def resolve(scope)
  MyClient.new.get(scope)
end

# controller code
# our "scope" is just a hash this time
render_jsonapi({})
