403 HTML Error Code when sending request to lexica.art using Python

I need to get all image prompts from the https://lexica.art/?q=history request, but the website returns 403 error code when I am trying to send a request.
I already tried to set User-Agent property, and copied all the request properties, but it still isn't working.
Here is my code:
import requests
url="https://lexica.art/api/trpc/prompts.infinitePrompts?batch=1&input={%220%22%3A{%22json%22%3A{%22text%22%3A%22history%22%2C%22searchMode%22%3A%22images%22%2C%22source%22%3A%22search%22%2C%22cursor%22%3A250}}}"

}
r=requests.get(url, headers=headers)
print(r.status_code)

I used selenium library instead, everything is working fine

Python application calling Nse India URL getting stuck in Heroku

I have a python program that calls the nseindia.com and tries to fetch the indices data using the URL: https://www1.nseindia.com/live_market/dynaContent/live_watch/stock_watch/liveIndexWatchData.json"
This code is working fine on my system, but when I deploy this to Heroku it get stuck at the URL call.

response = requests.get(url=url, headers=headers)
print(response.json())
Any suggestions?

The response is a 401 unauthorized. I know it has something to do with the structure of the data being passed into the request. Anyone come across a similar issue?

Python - How to log into a website that has a 302 page (while also passing on a cookie) after the initial sign in?

So here is the basic login process mapped out (when you successfully login on the site) for a high level understanding. Below it is my code, that only gets me the first cookie, when I need the second cookie to access the JSON I need. I have a working code that currently gets me the file but the cookie (2nd cookie) expires after a week so it is not sustainable.
Step 1 - Purpose: Get first cookie that will be "c1" below
Request URL: https://www.fakesite.com/sign-in.html
Request Method: GET
Status Code: 200
Step 2 - Purpose: Use "c1" to make a POST request to obtain second cookie "c2" <<<<-Can't get past here
Request URL: https://www.fakesite.com/sign-in.html
Request Method: POST
Status Code: 302
Step 3 - Purpose: Use "c2" and auth_token (doesn't change) to GET the json file I need <<<I have working code when manually getting 7-day cookie
Request URL: https://www.fakesite.com/ap1/file.json
Request Method: GET
Status Code: 200

My code results in returning the first cookie over again when I try and print all of them . I feel like I have tried everything to no avail. When I try to go to the last site while directly logging in, I get a 401 because I need the first cookie to get the second cookie first.

Python Requests unable to get the site even after passing headers

I am trying to scrape an e-commerce site Myntra but the request keeps on loading without ever returning the result. I have tried passing headers to the request with different user-agents but still, it doesn't work. If a timeout parameter is added, the request times out but no success.
Here is the sample code I'm trying to execute
import requests
url = 'https://www.myntra.com'
s = requests.Session()
headers = {
'authority': 'www.myntra.com',
'method': 'GET',
'path': '/',
'scheme': 'https',
'accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
'accept-encoding': 'gzip, deflate, br',
'accept-language': 'en-US,en;q=0.9',
'cache-control': 'max-age=0',
# dnt: 1
'sec-fetch-dest': 'document',
'sec-fetch-mode': 'navigate',
'sec-fetch-site': 'none',
'sec-fetch-user': '?1',

}
response = s.get(url, headers=headers, timeout=10).content
print(response)
If I try to curl the same site, I get a 403 status code with the following output.
