You can use this code for a GET call from the cluster API Docs and look at the response field "state" to see the status. You will want to swap out the domain for your workspace's domain and the cluster ID of the cluster you are monitoring.

curl --netrc -X GET \
https://<DOMAIN>.cloud.databricks.com/api/2.0/clusters/get \
--data '{ "cluster_id": "1<CLUSTER ID>" }' \
| jq .

Hope this helps!

There's a clusters GET request you can make as part of the clusters API:

https://docs.databricks.com/dev-tools/api/latest/clusters.html#get

Dy doing a `GET` call using the cluster id

curl --netrc -X GET \
https://dbc-a1b2345c-d6e7.cloud.databricks.com/api/2.0/clusters/get \
--data '{ "cluster_id": "1234-567890-myclustID" }' \
| jq .

The response json will have a `state` tag which will look like this:

{
  "cluster_id": "1234-567890-myclustID",
  ...
  "state": "TERMINATED",
  "state_message": "Inactive cluster terminated (inactive for 120 minutes).",
...
}
