When you install the default distribution of the Elastic Stack, you receive a basic license. For the full list of free features that are included in the basic license, see: https://www.elastic.co/subscriptions
You can initiate a trial license only if your cluster has not already activated a trial license for the current major product version. For example, if you have already activated a trial for v6.0, you cannot start a new trial until v7.0. To check your trial status, use the get trial status API.
At the end of the trial period, the platinum features operate in a degraded mode. You can revert to a basic license, extend the trial, or purchase a subscription.
