Is there a way i can do advanced payments? like 5 cycles at the time?

pay.py supports passing in a cycle to get the details for payouts on that specific cycle. For example, python pay.py 170 will show payouts for cycle 170. You could run the script 5 times, once for each of the cycles you want to pay, and then run those commands to process all 5 cycles in one go.

But if you're looking for more advanced payment options you may want to look into something like TAPS or TRD.

Hi men! was testing to see if the pay.py was still working and something broke.... gave me this error...

python pay.py 206
Traceback (most recent call last):
File "pay.py", line 38, in
level = int(data['level'])
KeyError: 'level'

pay.py relies on the mystique.tzkt.io API to get information about the current state of the blockchain. Usually a call to https://mystique.tzkt.io/v3/head will return information about the current level (i.e., block number) for the blockchain. But right now it's returning only "Out of sync", which causes an error in pay.py because it doesn't expect to not get the information it is looking for.

As far as I'm aware, this problem is entirely in the hands of the folks at Baking Bad, who provide the Mystique API at tzkt.io, to fix. It's probably just a hiccup from the switch over to the Carthage upgrade which just went through.

I've contacted Baking Bad to make sure they're aware of the issue. Hopefully a fix will be coming shortly.

Alternatively, if you are aware of another working service which provides the same API, you can replace the API URLs in pay.py and it should calculate and process the payout information as usual.

EDIT: Seems to be working for me now. 👍
