Hi Sinan, If it's in the Dashboard, it sure comes from the Dashboard REST API (which is an API completely unrelated to the RESTful Module).
To check the Dashboard REST API, log in there and click on the top-right "?" menu, and in the dropdown, click on "API". That will lead you to the Swagger/OpenAPI spec of the Dashboard. You will likely want to explore the "/pool" and "/block" endpoints. The API page will give you ready-to-use curl commands (the only thing you'd need to renew, once expired, is the authorization token).
