I use the Amazon Products (Associates) Web Service API to get Kindle book data. Interestingly, the API is no longer returning any Kindle books. Kindle newspapers are still being returned. Is anyone here facing the same problem? There's an open thread on the API developers forum:

No response from Amazon yet. I wonder if this is a deliberate move to stop people from obtaining Kindle book sales information.
