Why use the official Narodowy Bank Polski rate?

A market rate is a moving target; the rate Narodowy Bank Polski publishes is a fixed, citable figure that stays put once printed — which is why invoicing, customs, audit evidence, and statutory accounting in Poland lean on it rather than on a live feed. Every response from this API carries the bank's own rate_date, and on days with no publication you get the most recent published table — the one compliance rules tell you to apply.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via PLN) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/nbp/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/nbp/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/nbp/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/nbp/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
