Cross-Border Transaction Cost Calculator
Cross-border payment cost calculator for AI agents — get the TOTAL landed
cost of an international payment (transaction_cost): FX spread + transfer fees +
settlement time, by payment method (wire/ACH/crypto/card/PayPal), so you know what
the recipient actually receives and which rail is cheapest. Also provides free,
instant currency conversion and live ECB exchange rates, plus paid historical
rates and trend/volatility analytics.
