The PubNub Websockets API provides a way to subscribe to a custom data channel and log all sent messages over that channel on the console, and allows you to publish your messages to your own channel as well. PubNub is a Push technology intended specifically for high-message-volume applications and games. It is a cloud-based, real-time messaging service for mobile phones, tablets, TVs, HTML5 web browsers and game consoles.
Twelve APIs have been added to the ProgrammableWeb directory in categories including Artificial Intelligence, Data Mining, and Auto. Some highlights are an API that returns data about Superheros from multiple sources, and an API that uses machine learning for crawling the web.
