# Arguments: <start> <end> <profile_id> <token>
# start and end are the first and last pin to be checked. zeros will be added by the script.
# the profile id can be found in the url url when you have to enter your pin
# the token can be found in any request which requires authentification. try a pin to get it for example.
# the token has to be entered without the "Bearer" in front of it.
