The OANDA Exchange Rates API (hereafter, the API) is a RESTful API, which provides access to OANDA’s daily exchange rate data. The API is accessed via HTTP, the protocol used by web browsers (and not FTP, which is used to provide access to files). Using the API, you may programatically request rates, which are delivered to you via HTTP, which you may process and save in a format that works for your organization.
