Das Plugin muss eine JSON-Struktur zurückgeben, welches eine Liste von Zeiträumen und Preisen enthält.
Die Datumsfelder müssen in der Form `YYYY-MM-DDTHH:MM:SSZ` und der Preis in der korrekten Währungseinheit (bspw. EUR) angegeben werden.
Siehe nachfolgendes Beispiel:

Seit Oktober 2025 veröffentlicht der EPEX Spotmarkt dynamische Stromtarife im 15-Minuten-Takt.
evcc arbeitet intern mit 15-Minuten-Intervallen.
Plugins können weiterhin Daten in stündlichen Intervallen liefern, diese werden automatisch in 15-Minuten-Intervalle umgerechnet.

Siehe nachfolgendes Beispiel mit 15-Minuten-Intervallen:

```js
