The Easy API is one of the fastest growing API services out there. We offer a service that allows you to use multiple API's without having to code for the specific interfaces. An example would be that we have both a Zip Code Radius location tool, and also offer SEOMoz. Instead of coding two different application methods, you just have to code one. One easy to use API that can do the work of all the others. It accepts a POST then will return well formed XML. We are going to be offering JSONP->JSON integration in 2011.
Asking the simple question to API maintainers of how scalable is your API seems to conjure some awkward pauses. The Easy API recently discovered how well equipped we were to handle a massive influx of requests to our system. Quickly it became evident that the system wasn’t able to handle over a million requests a month, and failed under heavy load. This article discusses programming, servers, and monitoring changes that helped bring The Easy API back online and into the next level. The techniques discussed played a critical role in helping The Easy API scale to over a million requests a month and growing rapidly.
