How this service works
Norges Bank daily exchange rate of one foreign currency in NOK (NOK per 1 unit of the currency), from Norges Bank's SDMX-JSON data API. Last N observations; business days only.
Output
A JSON object containing an array of dated NOK exchange rate observations (up to 30), each with a date and rateNok value, plus metadata: currency code, unit label (e.g. 'NOK per 1 USD'), source URL at Norges Bank, and a checkedAt timestamp.
Example use cases
NOK rate check for financial reporting
“I need to report our Norwegian subsidiary's USD revenues in NOK for the last 5 business days — can you pull the official Norges Bank USD/NOK exchange rates for those days?”
Monitor EUR/NOK for currency risk
“What have the EUR to NOK exchange rates been over the last 10 days according to Norges Bank? I want to track any significant moves.”
GBP/NOK rate for travel budgeting
“How much is 1 British pound worth in Norwegian Krone right now according to Norges Bank? Show me the last 3 daily rates.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/norges-bank-norway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, official Norwegian Krone exchange rate data sourced directly from Norges Bank — ideal for compliance, financial reporting, or any use case requiring a central bank reference rate. Prefer this over commercial FX APIs when official Norwegian government data is required. The pay-per-call model with no signup makes it suitable for infrequent or automated agent use.
Side effects
- Invalid or unsupported currency code returns an error or empty rows
- Requesting more than 30 observations may be rejected or clamped
- Norges Bank data unavailable on weekends/holidays may result in gaps in the date series
- Payment failure via x402 means the call is not charged and no data is returned
- Malformed query parameters may result in a 400-level error
