Zend_Service_Amazon - Zend_Service
Zend_Service_Amazon is a simple API for using Amazon web services. Zend_Service_Amazon has two APIs: a more traditional one that follows Amazon's own API, and a simpler "Query API" for constructing even complex search queries easily.
Zend_Service_Amazon enables developers to retrieve information appearing throughout Amazon.com web sites directly through the Amazon Web Services API. Examples include:
Store item information, such as images, descriptions, pricing, and more
Customer and editorial reviews
Similar products and accessories
In order to use Zend_Service_Amazon, you should already have an Amazon developer API key aswell as a secret key. To get a key and for more information, please visit the » Amazon Web Services web site. As of August 15th, 2009 you can only use the Amazon Product Advertising API through Zend_Service_Amazon, when specifying the additional secret key.
Your Amazon developer API and secret keys are linked to your Amazon identity, so take appropriate measures to keep them private.
Example #1 Search Amazon Using the Traditional API
In this example, we search for PHP books at Amazon and loop through the results, printing them.
Example #2 Search Amazon Using the Query API
Here, we also search for PHP books at Amazon, but we instead use the Query API, which resembles the Fluent Interface design pattern.

The Zend_Service_Amazon_Query class is an easy to use wrapper around this method.
Zend_Service_Amazon_Query provides an alternative
API for using the Amazon Web Service. The alternative
API uses the Fluent Interface pattern. That is, all calls can be
made using chained method calls. (e.g.,
The Zend_Service_Amazon_Query API uses overloading to easily set up an item search and then allows you to search based upon the criteria specified. Each of the options is provided as a method call, and each method's argument corresponds to the named option's value:
Example #7 Search Amazon Using the Alternative Query API
In this example, the alternative query API is used as a fluent interface to specify options and their respective values:
This sets the option
Category to "Books" and
