  **Using a dedicated deployment?**

  Replace `api.langdock.com` with `<your-deployment>/api/public` in all requests.

<Info>
  Langdock intentionally blocks browser-origin requests to protect your API key and ensure your applications remain secure. For more information, please see our guide on [API Key Best Practices](/en/admin/ai-adoption-and-rollout/best-practices/api-key-best-practices).
</Info>

This endpoint exports project usage data including activity metrics, involved users per project, and resource consumption statistics.

<Warning>
  For workspaces with user-level data disabled, the project owner email is excluded from exports to maintain privacy compliance.
