user34296: I want to make a faucet. But my problem is that I don't know how I can make my payouts. I would have a lot of little amounts (like 10'000 satoshis) to pay.
Is there an efficient way of doing thousands of those transactions without paying to much fees?
Do I have to make every transaction manually (in Python or in Java with the Blockchain API)?
Thanks for the answers.

user31844: This is a classic issue with faucets and thus there are services that can help you with this. E.g. check this
Behind the scenes those services use send_many as you already found out.

user34296: Thanks for all the visitors, which have thought about that.
I found now the solution for that problem. I use the blockchain.info API. There is an option to send to many addresses at the same time.
