django api for wordpress sites

I have a Django REST API App with several Endpoints and my users have a number of WordPress Websites. I would like my users to be able to send GET REQUESTS to any Endpoint and use the GET RESPONSES to programmatically create dynamic pages and content on their WordPress Websites. I WANT THIS DONE WITHOUT ANY PLUGIN.

below is a video that better explains the requirement:

1. how will you implement the requirement?
2. how long will it take you to deliver?
3. what's your price?

kindly answer the above questions in your proposal.

thanks
