Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — danmarks-nationalbank-exchange-rate:

npm install danmarks-nationalbank-exchange-rate
import { getRate } from 'danmarks-nationalbank-exchange-rate';

const pair = await getRate('USD', 'DKK', { 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 Danmarks Nationalbank rate?

A market rate is a moving target; the rate Danmarks Nationalbank publishes is a fixed, citable figure that stays put once printed — which is why invoicing, customs, audit evidence, and statutory accounting in Denmark 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 DKK) 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.
