#zpr.io https://zapier.com/zapbook/updates/30/zprio-shortener/

Now your tweets have pre-shortened zpr.io URLs, no more failed tweet attempts due to crazy long URLs!
(We also don't re-shorten common shorteners like bit.ly or t.co.)
zpr.io is not a URL service that just spits out any shortened URLs, one must first set up twitter integrations using their website, and when tweeting a URL the user has the option of applying Zapier's URL shortening service automatically (enabled by default). A free account can use 1 "zap" (integration) and twitter is available for free.
