UTRUST has a bold vision: to be the PayPal of cryptocurrencies. The Swiss startup has a number of APIs in beta, and plans on launching a publicly available crypto payment platform in early 2019. The platform will enable both online and brick and mortar merchants to accept cryptocurrency payments.
The app55 API lets online and bricks and mortar merchants in the UK take payments from customers on any device, on websites designed and controlled by the retailer. app55 joins 362 payment APIs in our directory.
