Article
03/06/2024

Warning

The API Currency Service is available to clients solely to reconcile amounts paid or received by them resulting from their transactions through the Xandr Platform and may not be used by clients for any other purpose.

This is a read-only service that shows you the list of currencies that you can set a line-item or insertion-order to use.

REST API

HTTP Method	Endpoint	Description
`GET`	`https://api.appnexus.com/currency`	View all available currencies
`GET`	`https://api.appnexus.com/currency?code=CURRENCY_CODE`	View a specific currency
`GET`	`https://api.appnexus.com/currency?code=CURRENCY_CODE&show_rate=true`	View a currency's exchange rate for today
`GET`	`https://api.appnexus.com/currency?show_rate=true&code=CURRENCY_CODE&ymd=2012-03-01`	View a currency's exchange rate for a day in the past

Note

Exchange rates are sourced once daily from Oanda at approximately 3:00 a.m. UTC.

JSON fields

Fields	Type	Description
`as_of`	string	The date and time that Oanda last updated the exchange rate in UTC. We pull the rates from Oanda every day at 3:00 a.m. UTC. This is returned only when you pass `show_rate=true` in the query string.
`code`	string	The code for the currency.
`description`	string	A description of the currency.
`is_exposed`	boolean	If `true`, the currency is exposed.
`last_modified`	string	The date and time when the currency was last modified. (See Note *)
`name`	string	The full name of the currency.
`position`	enum	Whether the currency symbol appears before or after the amount. Possible values: `"before"` or `"after"`.
`rate_per_usd`	double	The exchange rate. This is returned only when you pass `show_rate=true` in the query string.
`symbol`	string	The symbol for the currency, e.g. `"$"` for USD

Note

To show conversion rates, pass show_rate=true in the URL. You can also retrieve a past day's rate by passing in ymd=YYYYMMDD via the URL.
* When querying the currency API (eg: rate_per_usd), the service returns all the correct values, with the exception for last_modified. The actual rates are accurate, and the API returns updated exchange rates.

Use the as_of column instead of last_modified to know the version of the exchange rate being returned.
