Invoking function exposed by a Model API via a script

Please find code below to invoke the Model API from a script :- 

seed(373)
iterations=1000

class Constants:
    MODEL_API_URL = "URL"
    KEY = "KEY"

class payload_setter:
    numeric_range=(1000,100000)

    payload = {
        "area" : {"range":numeric_range}
    }
class Data_Generator:
    @staticmethod
    def generate_payload(payload_value):
        numerical_range = sorted (payload_value.get("range"))
        return randint(numerical_range[0],numerical_range[1])+randint(1,9999)/1000

    @classmethod
    def callable(cls):
        return{
            payload : cls.generate_payload(payload_value) 
            for payload, payload_value in payload_setter.payload.items()

        }


class api_invoker:
    @staticmethod
    def return_response(response):
        print(response.json())
    @classmethod   
    def make_req(cls,req_payload):
        response = requests.post(
        Constants.MODEL_API_URL,
        auth = (Constants.KEY,Constants.KEY,),
        json={"data":req_payload}
        )
        cls.return_response(response)

for i in range(1000):
    payload = Data_Generator.callable()
    api_invoker.make_req(payload)

You should be able to get the URL and KEY from under the tester section (curl/java) of the Model API overview page.
