  title: dLocal FX Preview and Pay
  summary: Preview the exchange rate for a corridor, then create a payment in the local currency.
  description: >-
    Previews the conversion rate before charging. The workflow retrieves the
    real-time exchange rate between the settlement currency and the local
    currency, then creates a payment in the local currency for the target
    country. This lets a merchant show the customer the live FX rate before the
    charge is placed. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
