Magyar Nemzeti Bank (MNB) Get Currencies

See more REST Misc Examples

The Magyar Nemzeti Bank (MNB) is the central bank of Hungary. In this role, its primary objective is to achieve and maintain price stability. The MNB website is available to visitors in both Hungarian and English. The MNB provides the Arfolyam (trans. Exchange Rate) API, which can be used to retrieve current and historic currency exchange rates. This service uses SOAP calls issued in XML format.

This example gets a list of currencies.
