cupiu-bnr

Official BNR (National Bank of Romania) exchange rates in Python — zero dependencies.

Pulls the daily curs valutar BNR reference rates straight from the National Bank's public feed. Pure standard library, works on Python 3.8+, installs in one line. Built and maintained by the team behind cupiu.ro — where you can see the same rates with live charts and the full 2005→today history for humans.

Install

pip install cupiu-bnr

Library

import cupiu_bnr

rates = cupiu_bnr.latest()          # today's official reference rates
print(rates["EUR"].ron_per_unit)  # Decimal('5.2411')

# Convert between any two BNR-listed currencies (crossed via RON)
cupiu_bnr.convert(100, "EUR", "USD")

# History straight from the BNR archive
for day in cupiu_bnr.year(2024):
    print(day.date, day["EUR"].ron_per_unit)

Rates use Decimal (never floats — this is money) and normalise BNR's multiplier convention automatically, so HUF, JPY, etc. are always per-single-unit.

Command line

cupiu-bnr                     # all of today's rates
cupiu-bnr EUR                 # 1 EUR = 5.2411 RON  (2026-07-15)
cupiu-bnr convert 100 eur ron # 100 EUR = 524.11 RON
# `cursbnr` works as an alias for the same command.

Why

BNR publishes one official reference set per banking day (~13:00 Bucharest). Every accounting workflow in Romania — PFA invoices (Art. 290 Cod fiscal), importers, bookkeeping — needs that exact number. cupiu-bnr gives you it programmatically; cupiu.ro gives you it in the browser with charts, per-currency pages and the historical archive.
