The kernel of the system. This goes between the Internet and your API giving you things you don't want to have to write yourself like authentication, throttling, and statistics collection. It's fast, secure and easy to setup. You'll need either the REPL or the API to configure it first.
$ sudo npm install -g apiaxle-proxy
$ apiaxle-proxy

The Repl

You probably want this first. The repl allows you to configure ApiAxle from the command line. Setting up an API and API keys ready for the proxy to work with is easy. It fires up an instance of ApiAxle's own HTTP API in the background and uses that to modify aspects of the system. Anything you can do in the REPL you can do programmatically with the API too.
$ sudo npm install -g apiaxle-repl
$ apiaxle

axle> key "05050c14643dc" create
axle> api "acme" create endPoint="localhost:81"
axle> api "acme" linkkey "05050c14643dc"


Bear with me, this gets a bit meta. This is ApiAxle's own HTTP API which gives you full control over your APIs and the API keys used to access them. You can view statistics about individual APIs and API keys from week long granularities right down to near-real-time hits at a second granularity.
$ sudo npm install -g apiaxle-api

$ apiaxle-api
$ curl "localhost:3000/v1/apis"
