# License expiration

Cortex XDR licenses are valid for the period of time associated with the license purchase. After your license expires, you have access to your tenant for an additional grace period of 48 hours. After the 48-hour grace period, you no longer have access and it is disabled until you renew the license.

For the first 31 days of your expired license, Cortex XDR continues to protect your endpoints and/or network and retains data in the Cortex Data Layer according to your data retention policy and licensing. After 31 days, the tenant is decommissioned and agent prevention capabilities cease.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xdr-3.x/cortex-xdr-3.x-documentation/readme/understand-cortex-xdr-license-plans/license-expiration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
