I want to know about Twitter search API V1 and V2 Plans.

I am using the Twitter Search API to get the tweets along with the retweet count and like count.
But I am bit confused API V1 and V2 Plans.

Please help me out with which plan I take to get the search results as per my need.
What I need to do is:

  • search popular tweets using keywords with Twitter Search API V2.
  • Display the retweet count and like count of the tweets.
  • Retweet and like a tweet and post it on Twitter app.
