PHP CurrencyFX Library

Hi all,

I'm happy to share the latest library I've been working on.

It is called CurrencyFX.

Let's check it out 😆


CurrencyFX is a PHP Library that helps you retrieve FX Rates from multiple online services, batteries-included 🔋🔋🔋


Requirement: PHP 8.1+

  • Additionally, Laravel 10 (for Laravel auto integration)

100% tested and covered under Unit, Integration & E2E tests (assert against the real services)


composer require shipsaas/currency-fx

# (Optional) For Laravel users
php artisan vendor:publish --tag=currency-fx-configs
Enter fullscreen mode Exit fullscreen mode

Supporting Services / Batteries


Simply initialize the class with the required parameters (which are the API Key, Credentials). And it is ready to use in no time.

$service = new CurrencyCloudService($host, $loginId, $apiKey);
$rateResponse = $service->getRates('USD', 'SGD');

if (!$rateResponse->isOk()) {
    // failed to get the rate from third party service
    // do something here

$rate = $rateResponse->getOkResult()->rate; // float (1.4xxx)
Enter fullscreen mode Exit fullscreen mode

Laravel Usage

(Please add the needful ENVs before using, check out the currency-fx.php for more info)

use CurrencyFX\Services\CurrencyLayerService;
use CurrencyFX\Services\ExchangerRatesApiIoService;

// use the global "app"
app(CurrencyLayerService::class)->getRates('USD', 'EUR');

// DI
class TransferService
    public function __construct(
        private ExchangerRatesApiIoService $rateService
    ) {

    public function transfer(): TransferResult
        $rateRes = $this->rateService->getRates('EUR', 'GBP');
        if ($rateRes->isError()) {
            return TransferResult::error(...);

        $rate = $rateRes->getOkResult()->rate;
Enter fullscreen mode Exit fullscreen mode

Final Words

Thank you, please give it a ⭐️⭐️⭐️ to support the project.

Don't forget to share with your friends & colleagues, so they can also build their own SaaS products as well 🚀
