Swap allows you to retrieve currency exchange rates from various services such as Fixer, Currency Data or Exchange Rates Data and optionally cache the results. It is integrated to other libraries like moneyphp/money and provides a Symfony Bundle and a Laravel Package.

QuickStart

$ composer require php-http/curl-client nyholm/psr7 php-http/message florianv/swap

use Swap\Builder;

// Build Swap
$swap = (new Builder())

    // Use the Fixer service as first level provider
    ->add('apilayer_fixer', ['api_key' => 'Get your key here: https://fixer.io/'])
     
    // Use the currencylayer service as first fallback
    ->add('apilayer_currency_data', ['api_key' => 'Get your key here: https://currencylayer.com'])
    
    // Use the exchangerates service as second fallback
    ->add('apilayer_exchange_rates_data', ['api_key' => 'Get your key here: https://exchangeratesapi.io/'])
->build();
    
// Get the latest EUR/USD rate
$rate = $swap->latest('EUR/USD');

// 1.129
$rate->getValue();

// 2016-08-26
$rate->getDate()->format('Y-m-d');

// Get the EUR/USD rate 15 days ago
$rate = $swap->historical('EUR/USD', (new \DateTime())->modify('-15 days'));

We recommend to use the services that support our project, providing a free plan up to 100 requests per month.
