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

Usage examples

SEK quoted against USD and EUR

package main

import (
	"context"
	"encoding/json"
	"os"

	"github.com/peterhellberg/fixer"
)

func main() {
	resp, err := fixer.Latest(context.Background(),
		fixer.Base(fixer.SEK),
		fixer.Symbols(
			fixer.USD,
			fixer.EUR,
		),
	)
	if err != nil {
		return
	}

	encode(resp)
}

func encode(v interface{}) {
	enc := json.NewEncoder(os.Stdout)
	enc.SetEscapeHTML(false)
	enc.SetIndent("", " ")
	enc.Encode(v)
}

{

func main() {
	f := fixer.ExratesClient

	resp, err := f.At(context.Background(), time.Now(),
		fixer.Base(fixer.GBP),
		fixer.Symbols(
			fixer.SEK,
			fixer.NOK,
		),
	)
	if err != nil {
		return
	}

	encode(resp)
}

func encode(v interface{}) {
	enc := json.NewEncoder(os.Stdout)
	enc.SetEscapeHTML(false)
	enc.SetIndent("", " ")
