Below is the api response im getting:::

i need to save this file as jpg format locally to my system? could you please provide me a solution through python

Answer 1

You might have to decode the JSON-string (if not already done):

import json
json_decoded = json.loads(json_string)

Afterwards you can get the URL to retrieve and the filename from this JSON-structure

url = json_decoded['links'][0]['href']
local_filename = json_decoded['fileName']

Now you can download the file and save it (as seen here How to save an image locally using Python whose URL address I already know? ):

import urllib.request
urllib.request.urlretrieve(url, local_filename)
