[As of August 31, 2016, this API has been deactivated and this page is being maintained purely for historical and research purposes.] Freebase is an open database of the over 22 million real world entities like people, places, organizations and much more. It's built by the community and for the community free for anyone to query, contribute to, build applications on top of, or integrate into their websites.
The Freebase API is an aggregate of HTTP APIs that provide you with read/write access to the data stored in Freebase. The APIs support different use cases and allow you to get access the same Freebase data in many different ways. The search API returns freebase data given a free text user query. The search service indexes freebase data for any given entity, as well as other sources such as Wikipedia content.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
