We are based in the US and I don't think we will be eligible. From their FAQ -

Am I eligible to use MangoPay?

All companies registered in the European Economic Area can use our solution.

Hi I'm the founder of Mangopay. You can process payment in € $ £, and 7 other currencies on Mangopay. But you are right, you should have a company incorpored in Europe. Feel free to contact us! C.
