Send limits
Limits of how much this faucet can payout in a 30 minute window.
What is it? What a "30 minute window"?
How much your faucet can send in 30 minutes. For example if you set it to 0.001 BTC, that's how much the faucet will be able to spend between 12:00 and 12:30. The amount that faucet has spent resets every 30 minutes. If your faucet tries to spend more than that, API will return:
{"status": 450, "message": "This faucet exceeded it's safety limits!"}
We also plan adding email notifications to that and optional "paranoid mode" that will reset the API kay if the limit is hit.
It's meant to be a protection from hackers stealing all coins if they get the API key in their hands and mass attacks of bots.
For example
This site has a maximum of x satoshi every half an hour.
Currently you have to do that in the code of your faucet. Checking the error code and changing $ret['html'] around line 2355 in index.php should work.
However I think that customizing error messages is quite a nice idea, we'll think about implementing this in next version.
