Shareaholic can automatically shorten any link for you using a shortening service that you specify.

?url= (required; example: http://www.google.com/)
&service= (optional; tinyurl | bitly | jmp | google | shrlc)
&api_key= (optional)
&login= (optional)

https://shareaholic.com/v2/share/shorten_link?url=http://google.com/&service=google
