Ok here is the twitter API,
http://search.twitter.com/search.atom?q=perkytweets
Can any one give me any hint about how to go about calling
Use Meteor.http.get. Per the docs:
Meteor.http.get
Meteor.http.get(url, [options], [asyncCallback]) Anywhere Send an HTTP GET request. Equivalent to Meteor.http.call("GET", ...).
The docs actually include some examples of using Twitter, so you should be able to get started with them.
