To complete Kostas Pelelis's answer, because I had some difficulty to find the why the Response wasn't directly using the Action returned value.

Here is another version of FLASK class without decorators :

class EndpointAction(object):

def __init__(self, action):
    self.action = action

def __call__(self, *args):
    # Perform the action
    answer = self.action()
    # Create the answer (bundle it in a correctly formatted HTTP answer)
    self.response = flask.Response(answer, status=200, headers={})
    # Send it
    return self.response

class FlaskAppWrapper(object):

def add_all_endpoints(self):
    # Add root endpoint
    self.add_endpoint(endpoint="/", endpoint_name="/", handler=self.action)

    # Add action endpoints
    self.add_endpoint(endpoint="/add_X", endpoint_name="/add_X", handler=self.add_X)
    # you can add more ... 

def add_endpoint(self, endpoint=None, endpoint_name=None, handler=None):
    self.app.add_url_rule(endpoint, endpoint_name, EndpointAction(handler)) 
    # You can also add options here : "... , methods=['POST'], ... "

# ==================== ------ API Calls ------- ====================
def action(self):
    # Dummy action
    return "action" # String that will be returned and display on the webpage
    # Test it with curl 127.0.0.1:5000

def add_X(self):
    # Dummy action
    return "add_X"
    # Test it with curl 127.0.0.1:5000/add_X
