2. Get rates for a specific day.

latest and historical modes, respectively.

2. OpenExchangeRates
3. ExchangeRate - default

You can choose whatever you like by changing it in the property rate_exchanger of the config file.

In this case, you can add your own, 👀 see here for full details.

In order to get access to RateExchanger you can call the interface from Service Container like this:

use PostScripton\Money\Clients\RateExchangers\RateExchanger;

app(RateExchanger::class)->supports(['USD', 'RUB']);
app(RateExchanger::class)->rate('USD', 'RUB', now()->subYear());

Or you can use a cached variant because it implements the interface as well:

use PostScripton\Money\Cache\RateExchangerCache;
use PostScripton\Money\Currencies;

app(RateExchangerCache::class)->supports(Currencies::getCodesArray());
app(RateExchangerCache::class)->rate('USD', 'RUB', now()->subYear());

app(RateExchangerCache::class)->clear(); // deletes all cached data
