System Status

The status API is a public-facing API for determining the status of components and subcomponents in the Knowi infrastructure. This endpoint includes an indicator - one of GREEN, YELLOW, or RED, as well as a human description of the blended component status.

Note: This is only available for On-Premise customers and requires additional configuration. Contact support@knowi.com for assistance.
