I'm trying to make a HTTP request but the website that I currently can reach from my Firefox browser response 503 error. Code itself is really simple. After some search in the net I added user-Agent parameter to request but it didn't help either. Can someone explain me how to get rid of this 503 error? Btw I want to make my own alert system based on prices of btc.

import requests

url = "https://www.paribu.com"
header ={'User-Agent': 'Mozilla/5.0 (Windows NT x.y; Win64; x64; rv:10.0) Gecko/20100101 Firefox/10.0 '}


response = requests.get(url,headers = header)
print(response)

    503 is service unavailable. In this case, it looks like the web page has a buffer screen which prevents you from scraping – usernamenotfound Dec 20 '17 at 17:04
  • 503 appeared on my first try. So I assume they didn't put me on the blacklist, I think as you said they blocked web scraping somehow. – erondem Dec 20 '17 at 17:11
  • I have the same issue. Using curl works fine, requests from Java and Chrome also work fine. So I think there is an issue in requests module. – Sergei Vasilenko Mar 04 '18 at 06:18

I had the same problem. Use this in your code.

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36',}
r = requests.post(url, headers=headers)
r.raise_for_status()

503 means the server is overloaded: https://httpstatuses.com/503

This is not an issue with your code, it is an issue with the server you are trying to access.

Status code 503 means that the server is down for maintenance. Just try again later.
