Not sure if this is the purpose of the invest() function, but I'm trying to have my script auto-valut/bank a certain amount of winnings after I'm at a specific point above the starting balance.

I've got it to call fine, and get the expected response, but it seems like both DuckDice and Wolf.Bet don't listen to the invest command and just carry on regardless.

Are there any specific sites that are known to work with a way to vault/bank money with a DiceBot command?

EDIT: I know there is the option to have a second account and just 'Tip' the money across to that account as required, but I'm not super keen on getting both accounts banned/locked and losing what I've got once I try to withdraw.

invest is a defunct function for sites that allowed you to invest in the sites bankroll, like just-dice and bitvest, and well it invested that amount. As can be seen on https://bot.seuntjie.com/features.aspx, it's not used anymore and not available for any site other than just-dice, and I'm not even sure it still works there...

There is no way to use a sites vault at the moment, that is something I plan to introduce with doormat/krygamesbot.
