# MNB

This package provides Pythonic access to the exchange rate API hosted by Magyar Nemzeti Bank (MNB, Central Bank of Hungary).

## Background

MNB exposes a publicly available exchange rate API as a SOAP service where they publish their official daily rate between Hungarian Forint (HUF) and most other currencies.

The official documentation of their API is [available here](https://www.mnb.hu/letoltes/aktualis-es-a-regebbi-arfolyamok-webszolgaltatasanak-dokumentacioja-1.pdf) (only in Hungarian).

```
pip install mnb
```
