# API Reference (/docs/api-reference)



For now, the API reference is provided through the live `Scalar` documentation exposed by the platform services.

The sub-domain stays the same across environments. Only the cluster base domain changes.

Use the DNS of your own platform deployment. The examples below are intentionally environment-agnostic.

CoreAI API [#coreai-api]

* `https://llm-backend.<platform-domain>/scalar`

Model Installer API [#model-installer-api]

* `https://model-installer.<platform-domain>/scalar`
* `https://model-installer.<platform-domain>/scalar#tag/authentication`

Notes [#notes]

* use the DNS of your target cluster or environment
* the host pattern stays stable even when the environment changes
* for integration guidance, start from [Development](/docs/development) and [CoreAI API](/docs/coreai/components/coreai-api)
