Run EmberJS and Django on the same server and port

I want to run EmberJS and Django on the same server for avoid to have cross-domain requests.

So, for exemple, I want to run EmberJS on

exemple.com:80

and Django REST API on

exemple.com:80/api/

I normally start ember with command ember serve --port 80 and a run django with command python manage.py runserver 0.0.0.0:8000. But doing this the two server are on different domain and I have cross doman problems.

How can I do to run all two on same server with same port?

Thanks in advice!
