Platform API is one of 7 APIs that [Cloud Native Buildpacks](https://apis.io/providers/cloud-native-buildpacks/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Lifecycle, Platform, and Specification. The published artifact set on APIs.io includes API documentation.

The Platform API is the contract between the CNB lifecycle and a platform such as pack, kpack, or a CI runner. It defines how builders, stacks, run images, and inputs are passed to the lifecycle phases (analyze, detect, restore, build, export, and rebase) and how outputs are consumed.
