    `ExchangeRate` objects allow you to determine the rates that Stripe is currently
    using to convert from one currency to another. Since this number is variable
    throughout the day, there are various reasons why you might want to know the current
    rate (for example, to dynamically price an item for a user with a default
    payment in a foreign currency).

    Please refer to our [Exchange Rates API](https://stripe.com/docs/fx-rates) guide for more details.

    *[Note: this integration path is supported but no longer recommended]* Additionally,
    you can guarantee that a charge is made with an exchange rate that you expect is
    current. To do so, you must pass in the exchange_rate to charges endpoints. If the
    value is no longer up to date, the charge won't go through. Please refer to our
    [Using with charges](https://stripe.com/docs/exchange-rates) guide for more details.

    - *localize prices for processing payments on Stripe*
    - *reconcile Stripe transactions*
    - *determine how much money to send to a connected account*
    - *determine app fees to charge a connected account*

    *Using this Exchange Rates API beta for any purpose other than to transact on Stripe is strictly prohibited and constitutes a violation of Stripe's terms of service.*
