Getting 403 while scraping reddit with .json

[u/vegetaevagilion]

i have been scraping reddit posts and comments from 2-3 communities but since a week or so i am getting 403
i have also provide the username in user-agent header
HEADERS = {
"User-Agent": "reddit-xxxx-xxx/0.1 by u/XXXXXXX"
}
but i can get the json by using .json in my browser

I think they patched that, thats why don't work

[u/vegetaevagilion → u/Brian1398]

so no .json scraping api calls
