I’ve created a script in Python using the requests module to fetch the JSON response comprising tabular content visible on this website. However, the script always comes up with a 403 status code.

import requests

link = 'https://www.psacard.com/auctionprices/GetItemLots'

payload = {
    'draw': '1',
    'start': '0',
    'length': '25',
    'specID': '184637',
    'selectedGradeValue': '',
}
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36',
    'X-Requested-With': 'XMLHttpRequest',
    'Host': 'www.psacard.com',
    'Accept': 'application/json, text/javascript, */*; q=0.01',
    'Accept-Encoding': 'gzip, deflate, br, zstd',
    'Accept-Language': 'en-US,en;q=0.9',
    'Origin': 'https://www.psacard.com',
    'Referer': 'https://www.psacard.com/auctionprices/baseball-cards/1963-topps/1963-rookie-stars/values/184637',
}
with requests.Session() as s:
    s.headers.update(headers)
    res = s.post(link,data=payload)
    print(res.status_code)
    print(res.json())

How can I produce the JSON response using the script above?
