Steam Api Store Sales - node.js

Question

I would like to do a little script with nodejs that tracks interesting steam promos.
First of all I would like to retrieve the list of games on sale.
I tried several things, without success ...
GET request on the store.steampowered.com page (works but only displays the first 50 results because the rest only appears when you scroll to the bottom of the page)
Use of the API but it would be necessary to retrieve the list of all the games but it would take too long to check if each one is in promotion
If anyone has a solution, I'm interested
Thank's a lot

Answer 1

You can get the list of featured games by sending a GET request to https://store.steampowered.com/api/featuredcategories, though this may not give you all of the results you're looking for.
import requests
url = "http://store.steampowered.com/api/featuredcategories/?l=english"
res = requests.get(url)
print(res.json())
You can also get all the games on sale by sending a GET request to https://steamdb.info/sales/ and doing some extensive HTML parsing. Note that SteamDB is not maintained by Valve at all.
Edit: The following script does the GET request.
import requests
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:88.0) Gecko/20100101 Firefox/88.0',
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8',
'Accept-Language': 'en-US,en;q=0.5',
'DNT': '1',
'Alt-Used': 'steamdb.info',
'Connection': 'keep-alive',
'Upgrade-Insecure-Requests': '1',
'Cache-Control': 'max-age=0',
'TE': 'Trailers',
}
response = requests.get('https://steamdb.info/sales/', headers=headers)
print(response)
