from apium import af


class Hello(apium.Method):
    name = af.Str(required=True)
    age = af.Int(default=18)

    def execute(self):
        return {'msg': f'Hi {self.name}, you are {self.age}'}

Edit urls.py in your django project:

from django.urls import path
from apium.handlers.django.handler import api_handler

urlpatterns = [
    # ... your other path, e. g. 'admin/'
    path('api/', api_handler),
]

#!/usr/bin/env python
from flask import Flask
from apium.handlers.flask.handler import api_handler


app = Flask(__name__)
app.add_url_rule('/api/', view_func=api_handler, methods=['POST'])
app.run('localhost', 8080, debug=True)
