Yes, there is a site called faucethub.io that is widely used by faucet owners to process micro payments. They have an API for faucet owners to use that works well. In addition, they have a basic faucet script for you to use to start off.
Self advertisement, but I also have a faucet script for sale if you are looking for one.
Good luck with your faucet!
Well the first thing is to look through common users problems, and find a way to solve that problems with your product. That is the first checkpoint when you are trying to create something
About payments, there are a lot of exchangers and payment systems which offers transaction services and open API
Thanks for those.
I saw recently epay.info and faucethub.io, what would you recommend?
And also, can I say when the payments should be made?
For example I want manual withdrawal requests of the users but they should automaticly get withdrawn through the API.
Is that possible?
(User claims 1000 Satoshi, min. withdraw amount is 10.000 satoshi. Is that possible?)
Thank you!
