[![Version](http://img.shields.io/packagist/v/florianv/swap.svg?style=flat-square)](https://packagist.org/packages/florianv/swap)

Swap allows you to retrieve currency exchange rates from various services such as **[Fixer](https://fixer.io/)**, **[Currency Data](https://currencylayer.com)** or **[Exchange Rates Data](https://exchangeratesapi.io/)** and optionally cache the results. 

It is integrated to other libraries like [moneyphp/money](https://github.com/moneyphp/money) and provides

a [Symfony Bundle](https://github.com/florianv/FlorianvSwapBundle) and a [Laravel Package](https://github.com/florianv/laravel-swap).

## Sponsors

    // 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

    // 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'));
