VAT White List (Poland) runs on your own machine — the client starts it, so there is no endpoint to ping. 471 installs a week from pypi. Last commit 27 Oct 2026.
Look up Polish VAT taxpayers by NIP, REGON or bank account and verify account associations.
Today is the operative word: we check VAT White List (Poland) every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
