### Usage
There are two possible usage scenarios:
1. get all Euro exchange rates as an array of objects
2. get only a specific currency exchange rate as a single object
#### All available rates
Using the HTTP query `?foreign=USD` (where USD is one of the available currency symbols) will provide only that specificly asked rate.
Response example:
```json
{"currency":"USD","rate":"1.0852"}
```
#### Single exchange rate
If no query is provided, all available rates are returned.
Response example:
```json
