For daily formats, this means that one full day will be returned. If also no start timestamp is provided, the current day in the local timezone is used.</p>\n        <h4>Discontinuation of endpoints</h4>\n        <p>Endpoint discontinuations will be preceded by an announcement at least six months in advance, indicated by setting the \"deprecated\" status to true.</p>\n        <h4>Data License</h4>\n        <p>Unless stated otherwise, the data provided by the Energy-Charts API is licensed under the <a href=\"https://creativecommons.org/licenses/by/4.0/\" target=\"_blank\">CC BY 4.0</a> license.
