| Tool | Description | Behaviour |
|---|---|---|
| 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. | Not declared |
| nbp_exchange_rate | Get the official NBP rate for one currency against PLN (Polish złoty) — the latest rate by default, or the rate in force on a historical date. 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. | Not declared |
| nbp_exchange_rates | Get a full NBP (Polish central bank) exchange-rate table against PLN — the latest published table by default, or the table in force on a historical 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. Rates data starts 2002-01-02. | Not declared |
| nbp_gold_price | Get the official NBP gold price — PLN per 1 gram of 1000-fineness gold. Latest price by default; or one historical date; or the last N quotes (last_n, max 255); or a start_date/end_date range (max 93 days per query). Published every business day.
