Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Bank (public) holiday dates for the UK, Ireland, France, Germany and Spain. Call list_regions first to learn the valid country and region keys, then next_bank_holiday or list_bank_holidays. England, Scotland, Wales and Northern Ireland differ. Each client gets a free daily allowance, after which calls cost a small x402 USDC payment.
