Any auth will grant the higher rate limit.
It is worth noting that
Thats 1 API request to get the first 100 follows, and then 1 API request to get their streams. (If you intend to get who you are following as your list of streamers)
Since under Helix you can look up 100 streams at once, so you might find 30 requests is sufficient. If your list is hardcoded, then you can lookup 3000 streams with ease. (Or 1500 if you do follows then streams and keeping to the rate limit)
IE
https://api.twitch.tv/helix/streams?user_id=foo&user_id=bar&user_id=flibble
