Ordering posts by menu_order doesn’t work out of the box with the WP REST API. To enable this you need to add a filter to rest_{post_type}_collection_params for each post type you want to order by menu_order.
Okay, so based on what we know, what are the steps to creating a REST API?
Set up Django
Create a model in the database that the Django ORM will manage
Set up the Django REST Framework
Serialize the model from step 2
Create the URI endpoints to view the serialized data
