This is a .NET instant answer library written in C# for the DuckDuckGo Instant Answer API. It was created by Tim Kelly. DuckDuckGo is a search engine that aims to protect the privacy of users who enter personal queries. It does not track users' behavior. DuckDuckGo's RESTful API displays responses in JSON and XML.
Last month Yahoo! announced BOSS, its Build Your Own Search Service, which "allows developers and companies to create and launch web-scale search products by utilizing the same infrastructure and technology that powers Yahoo! Search." The REST API allows developers to get results in XML or JSON format for web, news, and image search queries. Recently the official Yahoo! Search Blog showcased a handful of the best mashups that third-party developers created in BOSS's first month of operation.
