urlB.org updates for 2008-02-01:
- API calls "create", "info" will return target url mime type and size
- urlkeys are unique for each url (and API key). If you are using the web interface, this means that next time someone submits the same URL they will get the same short URL. If you are using the API, you will get a unique short URL for each pair of (url,apikey)
- the "send SMS" option has been removed since it was inactive anyway
More info on the API can be found here.
