How to read tweets without API authentication

Hello,

I just want to read and display some tweets. I am familiar with the twitter4j library, but it requires authentication.

I was thinking something like loadStrings() but it just spits out pure HTML. I'm not quite sure how I would go about parsing the text and extracting only the tweets.

Even the Rest API JSON from twitter doesn't let you make requests without authentication... e.g. try this: https://api.twitter.com/1.1/search/tweets.json?q=@twitterapi

What's the best way to do this?

Many thanks in advance
