You can use this API: https://rapidapi.com/xtwitter/api/twitter288

you can try it tweetSimpleUsingGET

We have user-feed here https://rapidapi.com/twttrapi-twttrapi-default/api/twttrapi

I tested the app you mentioned but couldn’t get the data.

According to Twitter API v1.1:
GET https://api.twitter.com/1.1/statuses/user_timeline.json
https://developer.twitter.com/en/docs/twitter-api/v1/tweets/timelines/api-reference/get-statuses-user_timeline

If you have this endpoint, I would definitely like to sign a contract.
thanks.
