  title: API Evangelist enhancements for Chronosphere State V1 API
  version: 1.0.0
extends: chronosphere-state-v1-api-openapi.json
x-generated: '2026-08-29'
x-method: generated
x-source: The base document is Chronosphere's own published OpenAPI 3.0.3, saved verbatim from https://docs.chronosphere.io/openapi/
  on 2026-08-29. It already declares the correct templated server and the ApiKeyAuth scheme, so this overlay
  adds only cross-references and the response statuses the contract omits.

      '401': Missing or invalid API-Token.
      '403': Token lacks the required role.
