Grid automatically selects the optimal rail based on currency, country, and amount. You don’t need to specify the rail in your API requests. For destinations without a local rail, create a SWIFT external account to pay out over international wire — see External Accounts.

Currency Conversion

Grid handles currency conversion automatically through the quote system:

Exchange Rates

Real-time rates: Grid provides live exchange rates based on market conditions
Rate locking: Quotes lock rates for 1-15 minutes depending on payment type
Transparency: Exact rates and fees shown before execution
No hidden fees: What you see in the quote is what you pay
