Per-station fuel prices in Europe: which countries actually allow commercial reuse?

A licensing question for other reusers — I'd be glad to be corrected on any of this.

Per-station fuel prices are published in most of Europe, but in our survey only three national registers allow commercial redistribution today: France, Spain and Italy (about 42,000 priced stations between them). Elsewhere the barrier is legal, not technical:

• Germany — redistributing the market-transparency data requires authorisation as a consumer information service, i.e. an application rather than an API key.
• Austria — the public service is limited by regulation to the five cheapest stations per query, with no bulk endpoint.
• Portugal — the priced portal's terms prohibit commercial use; the openly licensed distribution carries locations without prices.
• Croatia — a request for a machine-readable open-data release was refused.
• Lithuania — strong daily per-station data, marked all rights reserved.
• Cyprus, Slovenia, Denmark — open or newly obligated, and look buildable.

Two questions for anyone who has been down this road:

1. Has anyone obtained the German authorisation as a smaller reuser, and roughly what did it involve?
2. Is there a lawful redistribution path for Portuguese per-station prices that we have missed?

Since fuel is the largest variable cost in road freight, this seems like a case where the data exists and the reuse terms decide whether it is worth anything.
