### `effective_fuel_price`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
주유소 표시 가격(원/L)과 지역을 받아 그 지역 지역화폐로 결제할 때의 실질 가격을 계산합니다. 선할인형은 가격×(1−할인율), 추가 충전형은 가격÷(1+적립률)입니다.
```

### `local_currency_for_region`

한국의 지역(시·군 또는 광역시)에서 쓰는 지역화폐와 이번 달 주유 할인율, 월 한도, 출처, 기준일을 알려 줍니다. 주유소별 가격은 주지 않습니다. 가격은 함께 돌려주는 OilPicker 링크에서 확인하도록 안내하세요.
```

### `oilpicker_link`

- The name "oilpicker_link" says "link": a word for a change.
