How to get json?

Question

In browser I got this. I'm trying to get json but got error:

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Code:

import requests
url = 'https://api-mainnet.magiceden.io/idxv2/getBidsByMintAddresses?hideExpired=true&mintAddresses=GXXBt4tzJ6aGoNvz87Xzh1PqXwB4qVRdQdHcX65iXtRZ&direction=1&field=2&limit=500&offset=0'
response = requests.get(url)
data = json.loads(response.text)
print(data)

Your response is empty. Why are you trying to load it as JSON? — OneCricketeer, May 01 '23 at 16:15

The response says access denied, you aren't getting the data. Try passing a user agent. Good luck. — Ξένη Γήινος, May 01 '23 at 16:24
I dont need content.Thanks for help.I want to get json the same as in the screenshot in my theme — alex, May 01 '23 at 16:44
`.content` or `.text` are the raw response from the server, which your error says they are empty, or **not JSON**. Requests does not send the same HTTP headers as your browser — OneCricketeer, May 01 '23 at 22:28

My personal preference would be:

import requests

URL = 'whatever'

with requests.get(URL) as response:
    response.raise_for_status()
    print(response.json()

raise_for_status() will raise requests.exceptions.HTTPError if the status code indicates some kind of error. Clearly, you might want to wrap that in try/except

Use builtin json function of the response

Also best practice to check status codes

response = requests.get(url)
if response.status_code == 200:
  data = response.json()
  print(data)
else:
  print("unexpected response")

Note this:

data = json.loads(response.text)

Response has a built-in method for this purpose. It's called as the json()

data = resp.Json()

Additionally, I would preface this with a conditional if check:

if resp.Ok:
    ...
else:
    print('NOK!')
    r.raise_for_status()
