Google Shopping API closes next week: do you have an alternative?

I've been talking with Semantics3 about using their API to give more results in a Google Glass shopping comparison hack I did recently: http://www.youtube.com/watch?v=6f9fh6vq6zs

It does look good and they've been very responsive. Some other APIs I've seen, though: http://www.scandit.com/ http://www.simpleupc.com/ https://developer.getinvisiblehand.com/ http://prosperent.com/ http://www.retailigence.com/

Some other APIs I've used are ShopSense ( http://www.youtube.com/watch?v=GwlABP0z_ms ) and Gilt ( http://www.youtube.com/watch?v=UYprO-9rrmQ ), although those are fashion and home. Others have mentioned using the Sears API.

Would you be comfortable sharing the traffic numbers on your site?

What do you mean, you shouldn't believe google? they said they were going to shut it down, and they're shutting it down. you can believe that.

if you mean you shouldn't trust google to maintain APIs forever, then yes. of course you shouldn't. you shouldn't build any product entirely on top of an API you don't have an SLA and lifespan guarantee for. doing so is irresponsible and unfair to your users, and when a free and un-promised API shuts down and breaks your product, you have nobody to blame but yourself.

Looks like Google has been shutting down features and apps that they think are not core to their business after the management shuffle and Page took over. And in their defense the announcement came pretty early.

If I were Google (or Twitter), I'd be satisfied with the competition-killing effects of publishing open APIs and shutting them down after a while, to the point of considering this an interesting defensive tactic. So much creative energy just dissipates instead of going into some possibly dangerous competing product...

To be fair, they announced the closing as part of the big "spring cleaning" post back in March. It's just now it's actually happening.
