Your challenge
Currency conversion continues to be a hidden source of friction in the buying journey
Customers abandon their carts when prices feel inconsistent, unclear, or unexpectedly high after currency conversion. For e-commerce platforms, brands, and payment providers, having access to reliable exchange rate data is essential for transparent pricing, fair transactions, and international growth.
Developer challenges
Outdated or approximate FX rates that confuse customers
Lack of pricing transparency, leading to cart abandonment
Inability to support emerging market currencies or new digital assets
Manual currency conversion logic that doesn't scale with SKUs or countries
Unclear historical conversions that affect refunds, taxes, or reporting
