404 response when creating audience for non-network account

Hello, I am trying to create an audience list for a non-network account and received a 404 response:

{"http_status":404,"message":"account","message_code":"api.action.resource_not_found"}

I don't get the same response when I create an audience list for the network account and can see the created audience in the portal. Is it possible to create audience lists within the API to non-network accounts?
