  22. MindMeister just launched a new API too:

  23. Vimeo.com recently released a full API too: http://www.vimeo.com/api

  56. Please at the Twilio API for voice / cloud telephony: http://www.twilio.com

    Twilio provides a telephony infrastructure web service “in the cloud”, enabling web programmers to integrate real-time phone calls into their applications. Twilio’s simple, powerful API minimizes the learning curve required to build advanced, reliable voice communications applications that solve critical business needs.

    Twilioʼs simple Pay-As-You-Go pricing model means customers pay for capacity only when they need it, not before. Voice applications written on Twilioʼs cloud solution scale transparently, eliminating programming, operational and contractual headaches frequently associated with rapid growth or traffic spikes.

    See how it works here: http://www.twilio.com/how-twilio-works
