Does anyone have a better way to check for stock? I was sending a get request to https://api-prod.nvidia.com/direct-sales-shop/DR/products/en_us/USD/5438481600 which would return a json response which would tell you inventory status, but now it doesn't work so well (error 503 - gateway times out).

Nvidia's own website makes the same website and now it fails there too, but eventually after a while the out of stock button pops up on their site. Do you guys think their website is setup so that if the request fails the out of stock button shows up? Or is their a better way to check for stock?

import requests

url = "https://api-prod.nvidia.com/direct-sales-shop/DR/products/en_us/USD/5438481600"

payload = {}
headers = {
  'authority': 'api-prod.nvidia.com',
  'accept': 'application/json, text/javascript, */*; q=0.01',
  'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36',

  'accept-language': 'en-CA,en-GB;q=0.9,en-US;q=0.8,en;q=0.7'
}

response = requests.request("GET", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

This should help:

from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))

import requests
import json

payload = {}
headers = {

}

url = "https://api-prod.nvidia.com/direct-sales-shop/DR/products/en_us/USD/5438481700"

response = requests.request("GET", url, headers=headers, data = payload)

/* print(response.json()) -- you can use this to look at the full dict */

jsonResponse = response.json()

for url in jsonResponse["products"]["product"]:
    print(" PRODUCT NAME:   ", url["displayName"], '\n', "IN STOCK?:      ", url["inventoryStatus"]["productIsInStock"].upper(), '\n', "PRODUCT STATUS: ", url["inventoryStatus"]["status"], '\n', "PRICE:          ", url["pricing"]["formattedListPrice"])
