Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — norges-bank-exchange-rate:

npm install norges-bank-exchange-rate
import { getRate } from 'norges-bank-exchange-rate';

const pair = await getRate('USD', 'NOK', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

Zero dependencies, TypeScript types included, and it runs anywhere fetch exists — Node 18+, Bun, Deno, and edge runtimes.

Why use the official Norges Bank rate?

When an auditor or tax office in Norway asks which rate you used, "the NOK mid-market rate at 14:32" is not an answer — the official rate published by Norges Bank for that date is. This API returns exactly those published figures, stamped with the bank's own rate_date; on weekends and holidays the most recent published table is returned, as compliance rules expect.

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

Endpoints

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.

Frequently asked questions

Is there an API for Norges Bank exchange rates?

Yes — this one. Official daily NOK rates as clean JSON, latest table on every plan including free.

How often does Norges Bank update its rates?

New tables land once per business day — the API picks each one up shortly after Norges Bank publishes it (latest: 2026-09-11).

Is this the official published table?

Yes — the rows are Norges Bank's published figures, untouched, with the original publication date attached. Pairs the bank didn't print are computed and flagged derived.
