In order for you to make OAuth-less api calls, the end point must not require auth (which this one does not), and you need a different base URL.
Instead of the http://api.twitter.com/1 as the base URL, try using http://twitter.com Like this: http://twitter.com/statuses/followers.xml?screen_name=noradio which works for me without any prompts for authentication. For a great online testing console, I highly recommend apigee: http://app.apigee.com/console/twitter It is hands down the best interface online to browse the full twitter api. -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
