A new API Discoverability search engine and a robots.txt type-format have been launched today at Gluecon. As API deployment continues to grow exponentially, API providers face increasing challeneges in getting their public APIs noticed, while API developer-consumers are facing more difficulties in discovering potential APIs that can add value to their supply chain.
Our API directory now includes 453 search APIs. The newest is the Automatton Instant Answers API. The most popular, in terms of mashups, is the eBay API. We list 220 eBay mashups. Below you'll find some more stats from the directory, including the entire list of search APIs.
