Need help with usage of stocktwits API for data

It seems If I make authenticaed calls I can get 400 requests per hour as opposed to 200:

https://api.stocktwits.com/developers/docs/rate_limiting

​

I don't quite understand how to make authenticated calls.

Most of the examples are for involve someone using your site, and requesting user's stocktwits profile data, so it involves redirecting to a site.

​

which is not really what I am after as I don't have a site.

So can anyone who has experience with using the API, give me some hints as to how I can make authenticated get requests?

Thank you.
