How we made an API for BoingBoing in an evening. Fluidinfo really is a fascinating piece of software. The team loaded in 11 years of BoingBoing content, allowing you to run structured queries against the data using their standard API, but also allowing users to attach their own information to the same corpus using Fluidinfo tags. Writable APIs are much less common than read-only APIs—Fluidinfo instantly provides both.
