Python unicodeDecodeError on parsing a JSON url

I am using python 3.4 and trying to parse what seems like valid JSON output from a url. ex: http://api.stackexchange.com/2.2/questions?order=desc&sort=activity&site=stackoverflow

This is what my code looks like

import json
from urllib.request import urlopen


def jsonify(url):
    response = urlopen(url).read().decode('utf8')
    repo = json.loads(response)
    return repo 


 url = jsonify('http://api.stackexchange.com/2.2/questions?order=desc&sort=activity&site=stackoverflow');

However, I get errors such as UnicodeDecodeError utf-8 codec can't decode byte 0x8b in position 1; invalid start byte

The script works with any other API, like github and so many others, but not with the stackexchange api

The response is compressed using gzip, you have to decompress it. 

$ curl -v http://api.stackexchange.com/2.2/questions\?order\=desc\&sort\=activity\&site\=stackoverflow
*   Trying 198.252.206.16...
* TCP_NODELAY set
* Connected to api.stackexchange.com (198.252.206.16) port 80 (#0)
> GET /2.2/questions?order=desc&sort=activity&site=stackoverflow HTTP/1.1
> Host: api.stackexchange.com
> User-Agent: curl/7.51.0
> Accept: */*
> 
< HTTP/1.1 200 OK
< Cache-Control: private
< Content-Type: application/json; charset=utf-8
< Content-Encoding: gzip

See the api.stackexchange docs for more details.

Example of decompression:

import gzip

def jsonify(url):
    response = urlopen(url).read()
    tmp = gzip.decompress(response).decode('utf-8')
    repo = json.loads(tmp)
    return repo
