A query must be send to address „http://185.38.248.171:8181/check_users/user1”, where „user1” is the username, to check whether given user is registered in Billon. If a user with the nick ‘user1’ is registered, we will receive following message in response:

{'user1': 'OK'}

Otherwise if the user is not registered:

{'user1': 'NOT_FOUND'}

There is the possibility of querying about several users simultaneously:

http://185.38.248.171:8181/check_users/user1,user2,user3,user4

The usernames have to be comma-separated! Then the response looks like this:

{'user4': 'NOT_FOUND', 'user2': 'NOT_FOUND', 'user3': 'NOT_FOUND', 'user4': 'OK'}

Only addresses approved by us can use this feature. Contact with us if you are interested in it.
