About Bulgarian National Bank

The Bulgarian National Bank, founded in 1879, is one of the world's oldest central banks. Following Bulgaria's adoption of the euro, it publishes euro-denominated reference rates for around 30 currencies each business day.

Node.js / TypeScript client

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

npm · bnb-exchange-rate GitHub · AllRates-Today/bnb-exchange-rate

npm install bnb-exchange-rate

import { getRate } from 'bnb-exchange-rate';

const pair = await getRate('EUR', 'USD', { 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 Bulgarian National Bank rate?

When an auditor or tax office in Bulgaria asks which rate you used, "the EUR mid-market rate at 14:32" is not an answer — the official rate published by Bulgarian National 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 EUR) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/bnb/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/bnb/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/bnb/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/bnb/availability — publication calendar: the dates the bank actually published (all plans)

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.
