Prometeo

Prometeo offers an API for cross-border banking, focusing on enabling businesses to manage international payments, verify accounts, and consolidate financial data. While it facilitates international payments and aims for efficiency and lower fees, it doesn't explicitly mention mid-market exchange rates or multi-currency accounts for holding balances in the same way Wise does for end-users. Its primary offering is an API for businesses to build their own solutions, rather than a direct multi-currency account for individuals or businesses to manage funds directly. However, it does emphasize transparent fees, fast transfers, API integration, batch payments (pay-outs), regulatory compliance, and customer support.
