MediaWiki-API-Ergebnis
Dies ist die HTML-Darstellung des Formats JSON. HTML eignet sich gut zum Debuggen, ist jedoch für die Verwendung in Anwendungen ungeeignet.
Gib den Parameter format an, um das Ausgabeformat zu ändern. Um die Nicht-HTML-Darstellung des Formats JSON anzuzeigen, setze format=json.
Weitere Informationen findest du in der vollständigen Dokumentation oder in der API-Hilfe.
