This API simply returns JSON readable exchange rate data from HNB (Croatian National Bank) since HNB only offers pure text which is useless for any programming task.
{
"currency_code": "036",
"currency": "AUD",
"unit": 1,
"rates": {
"buying": 4.971377,
"middle": 4.986336,
"selling": 5.001295
}
}
I intend to make a 2.0 version which will give the ability of calculating exchange rates via parameters.
