dinero

dinero is a Go client library for accessing the Open Exchange Rates API (https://docs.openexchangerates.org/docs/).

Upon request of forex rates these will be cached (in-memory), keyed by base currency. With a two hour expiry window, subsequent requests will use cached data or fetch fresh data accordingly.

Installation

go get -u github.com/mattevans/dinero

response, err := client.Rates.All()
if err != nil {
  return err
}
