Amazon.com released the latest version of its web services toolkit, a bundle intended to let developers tap into and repackage product information and other data from Amazon.com's website.
Syndication technology has been added to allow website maintainers to embed Amazon.com's shopping cart technology into their own sites.
Amazon.com's web services initiative is part of its extensive efforts to encourage outside parties to feature Amazon.com's merchandise on their own sites.
Participants in Amazon.com's seven-year-old Associates programme, which offers website owners a percentage of sales generated through their sites, can use Amazon.com's web services tools to add dynamic features to their sites, such as real-time pricing and availability information.
The tools can also be used by developers to create applications aimed at the growing ranks of suppliers either selling merchandise through Amazon.com or offering Amazon.com's wares on their own sites.
Amazon.com held a competition in late 2002 asking developers to create store-builder applications using its web services tools; the winning product, StorePerfect from WebWin Solutions, sells for $59.99 (£36.50).
More than 25,000 developers have enrolled in Amazon.com's free web services programme since its launch 10 months ago. The programme is available for the US-based Amazon.com website and for UK-based Amazon.co.uk.
Other country sites will be added to the programme in the future.
