Hi everybody,
a few days ago I had an idea to build a mobile app but, to do so, I need a service with an API allowing me to make several usd-btc and euro-btc changes, so I need a service with a fee as low as possible.
I know coinbase has an API, but I find 1% fee very high. Do you know any service with an API and a lower fee?
Thank you in advance.
If you want you can check this service :
