# API reference

> Use the stable v1 public contract for Continuous simulation resources.

The endpoint pages in this section come from the generated public OpenAPI contract.
Use them for exact request fields, response fields, errors, and authentication rules.

The production API base URL is `https://api.continuouslabs.ai`.
A Workspace API key uses the Bearer authorization scheme.
Each endpoint page lists every supported credential and required header.

<Note>
  A Simulation token authenticates only that Simulation data plane. It never authenticates a Continuous control-plane route.
