Tweet's Entities exclude a specific URL


#1

Here is my origin tweet: "hmm last test http://t.co/v0lkGuuhC2"
And here is the link to
https://twitter.com/capsuleworker/status/350268724797898753

After do serveral test with the streamming API, I think that Twiter API doesn’t consider the “http://t.co/v0lkGuuhC2” is an url…
Can anyone tell me why?

P/s: I’m using this endpoint https://dev.twitter.com/docs/api/1.1/post/statuses/filter
Pss: Sorry, I just see that link is a media, not link. Sorry for the noise!
