How current are the prices?

Prices are fetched on request and cached only very briefly. Every response carries the retrieval timestamp. We deliberately do not retain historical prices, as the terms of use of the source prohibit it.

Why does the average differ from individual stations?

The city value is a calculated mean across the open stations around the city coordinate. Individual stations can be well above or below it, which is why the response also carries the best price and the individual stations.

May I use the data commercially?

The licence permits commercial use with attribution. The terms of the source apply in addition: retrieval only on actual user action, no automated background polling and no permanent storage of prices.

Why are some cities missing?

Only cities with reported stations inside the search radius return values. For the others the response honestly reports that no data is available instead of inventing an estimate.
