Parsing Twitter's trending #hashtags using API 1.1 without OAuth

Question

It looks like with the API 1.1 update I can no longer fetch trending hashtags without using OAuth. Is there a way to this without logging into Twitter?

And if Twitter doesn't provide it (without OAuth) is there another reliable service I could use? Ideally I would like to get trending topics (#hashtags) for certain locations (city or country). Thanks!

Answer 1

Regarding the first question, you now must use OAuth for all API requests, hashtags included. See here.

In version 1.1, we will require every request to the API to be authenticated

I don't know about services, but why not use OAuth? You just need "application authentication", not the user to log in.
