Project Silk Road

Project Silk Road - “Project Silk Road” which is a collection of services, including a new version of the Live Search APIs for developer community – basically Search API 2.0 Beta + Search Ads pilot.

The Live Search API 2.0 Beta enables you to embed as a custom component a flexible and powerful search engine on your sites and applications. With the addition of XML (POX) and JSON formats, as well as the previously supported SOAP API, the Live Search API 2.0 Beta allows you to integrate the power of search using the code and formatting you choose.

Live Search API 2.0 exposes the power of the Live Search engine through an easy-to-use HTTP accessible endpoint, an RSS feed, or a SOAP API.
