Endpoint
GEThttps://saylorinnovations.com/api/fx/poland?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the official National Bank of Poland (NBP) mid-rate for PLN exchange rates or the NBP gold price in PLN per gram, particularly for Polish financial reporting, compliance, or accounting contexts that require the official central-bank rate rather than market spot prices. It is especially useful when you also need recent historical rate data in a single call.

- Invalid or unsupported currency code returns an error or empty result
- Days parameter outside 1–60 range may be rejected or clamped
- NBP data unavailable on weekends/holidays may return the last published rate or an error
- Network timeout if the upstream NBP API is slow or down
- Missing required payment header returns 402 Payment Required
