Fixer.io API Wrapper
====================

[![tests](https://github.com/Nacoma/fixer-io/actions/workflows/tests.yml/badge.svg)](https://github.com/Nacoma/fixer-io/actions/workflows/tests.yml)[![codecov](https://camo.githubusercontent.com/f10ee2a0a6f572b1c0826ae8bbdcbb5af33e76f8bb20248edbea8e5c97bdf558/68747470733a2f2f636f6465636f762e696f2f67682f4e61636f6d612f66697865722d696f2f6272616e63682f6d61696e2f67726170682f62616467652e7376673f746f6b656e3d425536583745354b394e)](https://codecov.io/gh/Nacoma/fixer-io)

A wrapper around [Fixer.io](https://fixer.io/)'s currency conversion rates API with minimal dependencies. Upgrading applications is always a hassle. This project aims to help relieve some of that pressure by depending exclusively on PSR interfaces instead of hard dependencies - while maintaining a comfortable API.

An additional goal of this project is to always deliver typed results. There's very little guessing about associative arrays involved when consuming this API.

Supported Endpoints

Usage
-----

[](#usage)

```
use Nacoma\Fixer\ExchangeFactory;
use Nacoma\Fixer\Http\Client;
use Nacoma\Fixer\Http\Middleware\ETagMiddleware;

$client = new Client(new Psr18Client(), [
    new ETagMiddleware(
        new SimpleCache(),
        new Psr17ResponseFactory(),
        new Psr17StreamFactory(),
    )
]);

$exchangeFactory = new ExchangeFactory(
    $client,
    new Psr17RequestFactory(),
    new Psr17UriFactory(),
    'your-access-key',
);

$exchange = $exchangeFactory->create('USD', ['EUR', 'JPY']);

// obtaining all rates
$result = $exchange->latestRates();

// manual conversion
$converted = 50 * $result->rates['EUR'];

// API endpoint conversion
$converted = $exchange->convert('USD', 'EUR', 50);
```

The optional `Nacoma\Fixer\Http\Client` is a thin Psr-18 compatible wrapper around any HTTP client. It enables custom middleware chaining in order to support caching via the `ETag` header.
