PLN → EUR / USD Price Converter

Browsing cars on otomoto.pl and doing the currency maths in your head? This extension adds the euro and dollar equivalent right next to every listing price. • Works on search results and on individual listing pages • Shows both currencies at once: 99 000 PLN → 22 958 € / 26 874 $ • Converts the car price only — monthly leasing and financing figures are left alone • Reduced prices: the old, struck-through price gets a struck-through equivalent too • New listings are converted as you scroll WHERE THE EXCHANGE RATE COMES FROM Rates come from the National Bank of Poland (Narodowy Bank Polski) — table A of average foreign currency rates, the official reference rate published every business day. The extension calls the bank's public API (api.nbp.pl) directly and caches the result for 12 hours, so browsing price pages costs no network traffic at all. The popup always shows which rate is in use: the value, the effective date and the NBP table number (for example 162/A/NBP/2026), so you can verify it against nbp.pl yourself. If the bank's API is unreachable, the last known rate is used, and you can enter a rate manually instead.
