Glue is a browser-based social network that connects friends around things they visit online. Glue appears on popular sites like Amazon, Last.fm, Netflix, Yahoo! Finance, Wine.com, Citysearch and many more, revealing friends and other Glue users interested in the same thing around the web.

Today, we are announcing the public availability of Glue API. The API enables 3rd party developers to build Glue applications, that leverage the way people connect with things around the web. The applications can leverage information from individual users as well as a rich set of aggregate popularity information.

The API is entirely REST based and relies on HTTP authentication. The developers need a Glue account to start using the API, and don’t need to request any special keys. Currently the API is free and limited to 5,000 calls per day. For more usage developers should email support@getglue.com.

Expanding Semantic Web API Family

Glue API joins the growing family of Semantic Web APIs. Previously, OpenCalais from Reuters enabled developers to automatically identify People, Places, Companies, etc. inside unstructured text. Zemanta API,similar in spirit, automatically identifies appropriate tags as well as related content around the web. Dapper API enabled developers to define the rules for extracting structured content out of the web pages. Freebase and Evri API’s enable developers to access dictionary topics in a structured way and to tap into relationships between the concepts.

Glue API compliments the existing Semantic Web API family in two important ways. First, it brings the exciting social dimension to the equation, revealing how people connect around things and concepts instead of pages. Secondly, Glue enables developers to get meta data and related links for books, music, movies, video games, topics, stocks, stars, artists, wine from hundreds of popular sites, turning these sites into databases.
