Yah, the api was probably added after your version. To my knowledge, there isn't a android app that uses something other then the SickBeard api for SickBeard. The good news is that SickBeard added the ability to update from the SickBeard web ui. So if you update your SickBeard the hard way this once, you shouldn't have to mess with anything again. You WILL back up your SickBeard before trying it though.

When I do http://domain:port/api/ I actually get a api response that looks like

{
"data": {},
"message": "API :: MyIpWasHere - gave NO API KEY. ACCESS DENIED",
"result": "denied"
}

So yah, you probably need to update. Go to "Config -> General" and look for the API section. If you don't find it, you gotta update.

EDIT: found the api release date info. It was added at SickBeard alpha 491. You have to update. BACKUP FIRST!!!! http://sickbeard.com/forums/viewtopic.php?f=3&t=3468
