Fixer.io API – Free Currency Converter Stopped Working

apicurrencycurrency-ratesmagento2.2.3

Magento ver. 2.2.3

Seems today fixer.io stopped working.
It was the only service that still works for currency rates.
If I try to reach the url from web browser I get this

You can still get a free account, but code change needed to make it works with new API.

Does anybody know if a fix coming with the next upgrade of Magento?

Alternatively in Magento 1.9.3.8 I'm getting currency rates from here, by custom module.

Does one already exist that use this service?

If there are no answers to these questions, the only solution will be to write a new custom module.

I hope for an escape…

EDIT:

as Bizzy Bee says:

Don't forget the following file to get it all going properly:

app/code/MyCompany/FreeCurrencyConverter/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'MyCompany_FreeCurrencyConverter',
    __DIR__
);
?>
