We actually had this (from that DB), but took it down because it isn't very comprehensive at all and often out of date. Might be better to query Amazon for them.

undone!

Doesn't seem to be working

I was looking for 044738018432 this time around.

perhaps you should query the upcdatabase.com, and if you don't get a valid response just don't return anything. If you do get a product than include it in the zero-click along with amazon.

Pseudocode:

If search may be a valid barcode
      then
            if barcode checksum is true
                  lookup on amazon
                        if true display amazon on zeroclick
                        fi
                  lookup on upcdatabase.com
                        if true display upcdatabase.com on zeroclick
                        fi
            fi
fi



here is an item nearby my desk in the database, Dust-off spray:

another item within reach that is in the database, a CD from an obscure local band called Marginal Man:

Here's what you will get forwared to when it's a valid barcode (passes checksum) but it not in the database (and I had to look long and hard to find a barcode that was not in the database, so saying it  "isn't very comprehensive at all and often out of date", isn't valid criticism as far as I'm concerned.  (BTW this is a package of Pork-Fu, which is something like pulled pork crossed with beef jerky and dental floss)

If you are feeling really generous, you could link to their "add new entry" page.
