When it comes to APIs there’s no shortage of information or, for that matter, opinions. In the hopes of bringing some clarity to that discussion, 3Scale has launched API Alchemy, a portal through which developers and other interested parties can discover relevant API content that has been vetted by the API management platform provider.
Our API directory now includes 239 messaging APIs. The newest is the Parseco API. The most popular, in terms of mashups, is the Twilio SMS API. We list 169 Twilio SMS mashups. Below you'll find some more stats from the directory, including the entire list of messaging APIs.
