Martini

kinda like the ultimate api mashup tool, pulls the scheme of the endpoint you are interested in and exposes all the services possible, i guess it's like an enterprise quality iffft but for your own products and services. kinda neat -- $75 a month so you better have a usage for it ;)

With endpoints available out of the box for the most common protocols and transports you'll be building sophisticated integrations between your legacy systems, databases and cloud-based applications faster than you ever thought possible
