If we are going to take things to the next level with APIs and AI, there are aspects of API operations we need to stop competing upon and start sharing. API Commons works in concert with APIs.json to turn human-readable API properties into machine-readable building blocks that can be used to standardize and automate your API ecosystem at scale.
