as Chris points out, it's still unofficial and URLs may change - Andy Baio

From 2005? - DeWitt Clinton

Argh, read the comments and the dates. I tried playing with that when he wrote it in 2005 and got nowhere. Was able to do some things, but not others. No responses from questions to the google reader google group. Unless there's a change, don't bother. - Karl Anderson

Try using the Ajax Feed API - http://code.google.com/apis.... This has been developed in the years since and provides nearly all of the Reader functionality that Niall was getting at, plus more. - DeWitt Clinton

Would love a way to do things like sync my del.icio.us and Google Reader URLs. Best way I found back then was del.icio.us to OPML and manually importing that in Reader, which kind of sucks. - Karl Anderson

DeWitt- you mean use the Ajax Feed API to re-implement Google Reader? No thanks :) Or do you mean that this API can add and remove feeds from my Google Reader account, similar to what Niall's article suggested that REST API could do? It didn't look like that from skimming the docs. - Karl Anderson

Oh, I meant for reading and discovering feeds, which was one of the things Niall uncovered with the Reader JS api. That functionality is now officially supported with the Ajax Feed API. I don't believe there is an official API for subscribing/unsubscribing yet. - DeWitt Clinton

The down side to the ajax feed api is that (to my knowledge) it doesn't allow you to get to reader's cached list, which ones you have or haven't read yet, or your existing feed list. I'm pretty sure there's an undocumented json api that reader uses, but I think it's about as stable as gmail's internal json api (i.e., not very). - Joel Webber

Our JSON API has been pretty stable, there's a few iPhone apps (e.g. Byline) and desktop clients (Feedly, ReadAir) that use it unofficially. Cleaning it up for official release is on our todo list. It's been there for three years, but it's still there. BTW, http://code.google.com/p... is a more recent set of unofficial docs than Niall's blog post. - Mihai Parparita

Sorry about that everyone, this popped up in my Google Reader and I didn't notice the year. Thanks for the update, Mihai. - Andy Baio

TGDaily has picked this story up as new, but didn't link because they noticed the year. Pretty lame. - Tom
