Api usage is simple. You don't need an API key (at least now) and there is no limit on usage (although we might limit if there is a very high use coming from a certain source or when our service is misused):

But - as of August 08th, 2013, you have to have your url whitelisted before you can use it. Send an email to api@byrk.de if you want to use our service.

Shorten an URL

To encode an URL fetch

https://byrk.de/api/?u=%%URL%%

where %%URL%% is your URL. The response you get is the shortened URL.

In case, anything goes wrong, you will receive the message FAIL
