About National Bank of the Republic of Belarus

The National Bank of the Republic of Belarus sets official Belarusian ruble exchange rates each business day — around 30 currencies, published in advance and effective the NEXT calendar day, so Friday's setting already carries Monday's official rate. It is the rate Belarusian accounting and tax legislation references; the bank also serves one of the cleanest open JSON APIs of any central bank.

Node.js / TypeScript client

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

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

const pair = await getRate('USD', 'BYN', { 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.

Full reference — installation, all four functions, response shapes, error codes: nbrb-exchange-rate documentation.

Why use the official National Bank of the Republic of Belarus rate?

When an auditor or tax office in Belarus asks which rate you used, "the BYN mid-market rate at 14:32" is not an answer — the official rate published by National Bank of the Republic of Belarus 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 BYN) 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.
