Flask REST Blueprint not found

I am trying to split up my app that uses Flask, Blueprint and REST in different components. But I cannot get the api to work.

The structure is as follows:

restml
|-> __init__.py
|-> app.py
\-> resources
    |-> __init__.py
    \-> hello.py

My restml/__init__.py is:

from flask import Flask
from flask_restful import Api

from restml.resources import hello

app = Flask(__name__)


app.register_blueprint(hello.blueprint)

if __name__ == '__main__':
    app.run(debug=True)

My restml/resources/hello.py is:

from flask_restful import Api, Resource, url_for
from flask import Blueprint

blueprint = Blueprint('hello', __name__)
api = Api()

class Hello(Resource):
    def get(self):
        return {
           "hello world"
        }

api.add_resource(Hello, '/api/hello', endpoint='hello')

When I run the the app everything starts but curl fails to retrieve from the url http://localhost/api/hello.

How should I adjust the files so that the REST api can be found?

Update

After adding 

import restml.resources.hello import blueprint

I get the following error

web_1    | Traceback (most recent call last):

You need to import your restml/resources/hello.py file in restml/__init__.py

from restml/resources/hello.py import blueprint

Should work.
