go-finance
This is a Golang library which contains finance related functions.
Exchange Rates
The following example explains how to use this package to retrieve the exchange rates from ECB:
€1 =", rate) } }">
package main import ( "fmt" "os" "github.com/pieterclaerhout/go-finance" ) func main() { rates, err := finance.ExchangeRates() if err != nil { fmt.Println("ERROR:", err.Error()) os.Exit(1) } for currency, rate := range rates { fmt.Println(currency, "-> €1 =", rate) } }
Checking VAT Numbers
You can also VAT numbers via the VIES service. The following sample code shows how to do this:
package main
import (
"fmt"
"os"
"github.com/pieterclaerhout/go-finance"
)
func main() {
info, err := finance.CheckVAT("BE0836157420")
if err != nil {
fmt.Println("ERROR:", err.Error())
os.Exit(1)
}
fmt.Println(info)
}
IBAN & BIC
There is also a function which converts a regular Belgian Bank Account Number to it's IBAN / BIC equivalent:
package main
import (
"fmt"
"os"
"github.com/pieterclaerhout/go-finance"
)
func main() {
info, err := finance.CheckIBAN("738120256174")
if err != nil {
fmt.Println("ERROR:", err.Error())
os.Exit(1)
}
fmt.Println(info)
}
