There are scads of them. These are pretty broad categories. Amazon has
apis for sdb, ecs, and aws, to name three. Google has numerous apis,
including calendar, map, search, reader, translate, etc.

But fundamentally, Ruby can access any service. You just have to
program it. In many cases someone already has.

Why are you trying to catalog public apis that people are interfacing
to using Ruby?
