Fetch the most recent Norges Bank exchange-rate reference for a currency against NOK — the canonical conversion benchmark Norwegian tax + accounting authorities accept for obligations in foreign currency (Årsregnskap, cross-border MVA, dividend reporting). The currency-of-record lookup; takes no Norwegian-company input. Returns the rate, the date it is valid for (weekday rates only; weekends / holidays return the prior business day's rate), and source attribution. Input: { base, quote, date? } — ISO 4217 codes, NOK-ANCHORED: exactly one side MUST be 'NOK'. A pair without a NOK side is rejected client-side as UNSUPPORTED_CURRENCY_PAIR — fetch both NOK legs and derive the cross rate yourself. Failure modes: VALIDATION_FAILED, UNSUPPORTED_CURRENCY_PAIR, INVALID_DATE, UPSTREAM_TIMEOUT, NO_RATE_AVAILABLE, SCOPE_INSUFFICIENT (needs read:norgesbank). For compliance obligations or filing deadlines rather than a currency rate, use get_company_summary instead. Docs: https://www.apier.no/docs/mcp
