4sp.in Shorten API

Just put your URL you want to shorten after http://4sp.in/shortenapi?url= and it will return the short link for it.
You must include the protocol, http:// ftp:// https:// AND the whole destination URL must be URLencoded.

Examples:
http://4sp.in/shortenapi?url=http%3A%2F%2Fwww.amazon.com%2Fgp%2Fproduct%2FB0029T4GAU%3F%26tag%3Dbraindonkey-20
or
http://4sp.in/shortenapi?url=http%3A%2F%2Ftwitter.com%2Fbraindonkey
or and example of a bad URL
http://4sp.in/shortenapi?url=http%3A%2F%2Fsomesite.company%2F
or another example of a bad URL
http://4sp.in/shortenapi?url=www.google.com%2F%23hl%3Den%26q%3Dbraindonkey Missing the http://

If the URL is valid and can be shortened, the API will return the short URL, nothing more.
If the URL is NOT valid, the API will return the word: ERROR.
