API Commons is where the open source building blocks of API operations live. API Commons began as a machine-readable artifact to define the licensing of your API, but has grown to support getting started, authentication, plans, SDKs, road map, change log, and support. API Commons works in concert with APIs.json, helping translate the human-readable properties of your API operations into machine-readable ones that can be used to automate your API ecosystem.
