Create a quote using senderAmount, senderCurrency, and receiverCurrency. Save data.id as quoteId. This call does not initiate a payment or create a transfer request.

Use the request's exact amount and currencies. Request creation uses amount and chargeCurrency; quote creation uses senderAmount and senderCurrency. The returned receiverAmount already includes the fee deduction. Use the returned expiresAt in Unix milliseconds rather than assuming a fixed validity period.

Sandbox uses the same suffix under /api/sandbox/b2b/cross-border/requests with a sandbox bearer token. Quotes cannot be shared between accounts or environments.

See Cross-border Quotes for confirmation, charging and retries.
