## API
To authenticate a user to Polr, you will need to provide an API key along with each request to the Polr API, as a GET or POST parameter. (e.g ``?key=API_KEY_HERE``)


### /api/v1/action/shorten

Arguments:

* ``url``: the URL to shorten (e.g https://google.com)
* ``custom_ending`` [not now supported] (optional): a custom ending for the short URL. If left empty, no custom ending will be assigned.

Short an URL
```
GET: http://example.com/api/action/shorten?key=API_KEY_HERE&url=http://example.de/shortening/main?q=5x

Response: 
{ "action": "shorten",
  "result": "https://example.com/5kq" }
```

### /api/v1/action/lookup

Arguments:

* ``url_ending``: the link ending for the URL to look up. (e.g 5ga)

Lookup for existing URL

```
GET: http://example.com/api/action/lookup?key=API_KEY_HERE&url_ending=5kq

Response: 
{ "action":"lookup",
  "result": {
        "long_url": "http://example.de/shortening/main?q=5x",
        "created_at": "2017-05-12 22:48:40.997520107 +0200 CEST",
        "clicks":"0" 
        }
}

## ToDo

* Add more Statistik details like the clicks from Country and Referer. 
* Implements the correct HTTP Error Codes
* Add config File
* Secure the API with API Key [optional]
