Wrong rate limit


#1

i am new to twitter API started working on it on php using the following library https://github.com/abraham/twitteroauth/

connecting to it and asking for user look up
$twitter = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
$twitter->host = “https://api.twitter.com/1/”;
$userInfo= $twitter->post( ‘users/lookup’, array(‘user_id’ => “”.$id)); // i am talking about this line

here i am calling users/lookup for each id i have (i know i can put multiple ids comma seprated) but i didn’t knew that before any way i notice i get the rate limit of 150 calls why i cant do more it should 350 calls since i am using Oauth , is this correct ?!
