You can do something like this:

 import requests
 import json


class Model(model.Model):
    url=models.URLField()
    price=models.FloatField()

    def save(self, *args, **kwargs):
        resp = request.gets(self.url)
        #assuming that json response looks like this: {'price': 2000} 
        resp_str = resp.content.decode()
        resp_dict = json.loads(resp_str)
        self.price = resp_dict.get('price')
        super().save(*args, **kwargs)

note: The code is not tested, but it is enough to give a general idea to proceed further.
