Technical details
Endpoint
GEThttps://saylorinnovations.com/api/fx/czech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the official Czech National Bank (ČNB) daily fixing rate for CZK, particularly for legal, accounting, tax, or compliance purposes where the CNB rate is the authoritative source. Prefer it over market-rate FX APIs when the Czech koruna is the base currency and official government-published rates are required. It covers ~30 major and regional currencies with daily granularity.
Side effects
- Invalid or unsupported ISO currency code returns an error or empty rates array
- Endpoint may be temporarily unavailable if the Czech National Bank has not yet published the day's fixing (e.g. early morning CET or weekends/holidays)
- Network or upstream data source outage returns a 5xx error
- Requesting a currency not covered by the CNB fixing (e.g. exotic currencies) returns no result for that code
