When searching Amazon using their API is there a way to separate out hardcover, paperback, kindle and pre-orderable books?
I'm using Ruby and Amazon Product gem and have been searching through their documentation looking for info on this and haven't managed to find anything yet.
I have come across some starting points that I am working through. There seems to a way to get this information via RrelatedItems ResponseGroup as described here. The KindleStore hierarchy seems relevant.
Binding is possibly the field I need to somehow look at and amazon's API provides a way of getting to AlternateVersions of an ASIN using the AlternativeVersion ResponseGroup type for books.
I will assume you know how to set up the Amazon Product gem request object correctly. from there, you can do...
search = req.search( 'Ender\'s Game' )
search.each('Item') do |item|
asin = item["ASIN"]
title = item['ItemAttributes']['Title']
hash = {
:response_group => ['ItemAttributes']
}
items = req.find( asin, hash )
items.each('Item') do |ia|
puts "[#{asin}]: #{title} => [#{ia['ItemAttributes']['Binding']}]"
end
end
which produces output like
