Go client for the Foreign exchange rates and currency conversion API 💰

fixer

Go client for Fixer.io (Foreign exchange rates and currency conversion API)

You need to register for a free access key if using the default Fixer API.

The default client loads its access key from the environment variable FIXER_ACCESS_KEY

Installation

go get -u github.com/peterhellberg/fixer

		fixer.Base(fixer.SEK),
		fixer.Symbols(
			fixer.USD,
			fixer.EUR,
		),
	)
	if err != nil {
		return
	}
