Connect model website with flask server running DQN algorithm (Deep Reinforcement Learning)

I have a model js based web application and a flask server running a DQN algorithm. I need to integrate the DQN algorithm with the model web site. The model website through a POST request sends JSON data to the flask server where the JSON data needs to be processed as inputs to the DQN algorithm and as a response to the POST request , the output of the algorithm should be passed into the front end web site.
