# Performing health checks The API server and the worker both have health check endpoints that you can use to check whether your Tonic Structural instance is available. ``` GET https:///health Response: 200 Healthy -or- 503 Unhealthy ``` If the service is up and all dependent resources can be reached, the response is `Healthy` with a status code of `200`. Otherwise, the response is `Unhealthy` with a status code of `503`. The logs for that container indicate the specific resources that could not be reached.
