Glue Stream is "Glue Live" and shows what is happening on Glue in real time. Glue Quilt shows trending topics over the past 7 days. Glue Spider shows connections between people and sites around the web.

Glue's API is part of an expanding group of semantic web APIs such as Reuters' OpenCalais, Dapper, Freebase, Evri, and Zemanta, all of which helped develop links and relationships between terms and concepts.

According to the company's website, the Glue API complements the existing semantic web family in two 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."

Currently the API is free and limited to 5,000 calls per day. For more usage developers should email support@getglue.com.
