How to get status code 200 instead of 401 from api calls json response

Before including user-agent as header I got 403 and after injecting user-agent I got 401. I'm not understanding How can I get 200 response.

Script:

import requests
import json
#url:https://www.barchart.com/stocks/quotes/MSFT/competitors?quoteSectors=-INO&page=1&orderBy=weightedAlpha&orderDir=desc
headers = {
    "x-xsrf-token": "eyJpdiI6IlhXSVFja0FhdzV1L3ZtRXBmbDFieXc9PSIsInZhbHVlIjoicUllR0hFL2NWbysxL2pjSVoyR2ZYYk03Zk42Qmh3MGJqckhSRUE3Vi9PREp1ME9jMVJlK2djSHNWRmVQWmcvRkxpM2VIUlFLTFZma2J2c2VLNDd5cGdJV0JnVEM2T0ZzUS9KTzJJSUFIWVlud0w0eGtyUzRRdHdlT2RKMVJPcFEiLCJtYWMiOiIzNjgxZTA1NTAyMjZiZGE2NGU1NmYwYjMxMTVjNjA3ZmU1Mjg0NTRjODA1OTdlNTZmYjU4YTFlNGFlMjkwZDQzIn0=",
    "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36"
    }

params = {
    "symbol": "MSFT",
    "lists": "stocks.inSector.all(-INO)",
    "fields": "symbol,symbolName,weightedAlpha,lastPrice,priceChange,percentChange,highPrice1y,lowPrice1y,percentChange1y,tradeTime,symbolCode,symbolType,hasOptions",
    "orderBy": "weightedAlpha",
    "orderDir": "desc",
    "meta": "field.shortName,field.type,field.description,lists.lastUpdate",
    "hasOptions": "true",
    "page": "1",
    "limit": "100",
    "raw": "1"
    }

api_url = 'https://www.barchart.com/proxies/core-api/v1/quotes/get?'
s=requests.Session()
req = s.get(api_url, headers=headers, params=params)
print(req)
