Use this endpoint to lock an exchange rate before creating a transfer. Quotes give the customer a deterministic source-to-destination conversion rate that’s valid for a fixed window (30, 60, or 300 seconds). The quote captures the source amount, destination amount, exchange rate, and full fee breakdown (integrator + platform) at the moment of issuance. A quote can be redeemed exactly once by passing its ID when calling Create Transfer.
Quotes are most useful for trading and cross-border payouts where the customer needs to see the exact rate they’ll receive before committing the transfer. For floating-rate transfers (e.g. payroll, treasury rebalancing), skip the quote and call /v2/transfer directly.
