nbp_convert

Convert an amount between two currencies using official NBP mid rates, cross-rated through PLN. Supports PLN and every currency NBP quotes: table A is used first and table B (exotic currencies, published Wednesdays) is consulted automatically for codes A doesn't carry — each side of the response shows the rate, table and effectiveDate used. Latest rates by default, or historical with date. NBP publishes only on Polish business days — on weekends/holidays the request falls back to the most recent preceding publication; effectiveDate in the response shows the date actually used.

Tables 'a'/'b' return the mid rate; table 'c' returns bid/ask. NBP publishes only on Polish business days — on weekends/holidays the request falls back to the most recent preceding publication; effectiveDate in the response shows the date actually used. Use nbp_rate_series for a multi-day history.

date	string	Optional historical date (YYYY-MM-DD). Omit for the latest rate.

no_cache	boolean	Force a fresh NBP fetch and bypass this server's result cache. Default false.
