## Market quality codes

Each market stamps quality on the wire in its own vocabulary.
The API maps each market's quality level to a shared ladder per the table below.

| Quality       | DE Level                 |
| ------------- | ------------------------ |
| `provisional` | Z18 Vorläufiger Wert     |
| `estimated`   | 67 Ersatzwert            |
| `calculated`  | 79 Energiemenge summiert |
| `measured`    | 220 Wahrer Wert          |
