besuche WSFINDER.com: Welcome! This is a community effort to create a list of all APIs and web services that are publicly available for people to play with. We’ve seen the great things that people have done with Open APIs. We hope to encourage more cool stuff to get built and for more companies and developers to open up their APIs. We think that the Web 2.0 world is approaching quickly and that this will accelerate it.
