When founding an empire the order of operations is first to fetch_captcha. Then create the empire. Then optionally update_species (default is human). Then finally call the found method to set up the empire on it's new home planet.
The following methods are available from /empire.
Returns a 1 if the name is available, or a throws an exception if it is not.
Throws 1000.
The name of the empire to search for.
Ends a session. Returns 1.
Throws 1006.
A session id.
Returns a hash like the following after confirming the password matches the empire.
NOTE: Once established, this session will stick around for up to 2 hours of inactivity. Therefore, you need not login again if you still have a valid session.
{
"session_id" : "id-goes-here",
"status" : { ... }
}Throws 1004 and 1005.

"url" : "'https://extras.lacunaexpanse.com.s3.amazonaws.com/captcha/id/id-goes-here.png"
}Creates a new empire and then returns an empire_id.
This is not the end of the story though. Now you must either create a update_species for this empire and then found it, or just skip the species part and found the empire.
Throws 1000, 1001, 1002, and 1014.
NOTE: If either captcha_guid or captcha_solution don't match what the server is expecting it will throw a 1014 error, and the data portion of the error message will contain new captcha information. You must use this. A captcha cannot be used more than once.
