	"github.com/DiFronzo/blockchair"
)

var clientID string

func init() {
	clientID = os.Getenv("API_KEY")
}

func main() {
	c := blockchair.New()
	c.APIKey = clientID // If you don't have an API key remove the lines about "clientID".
	resp, err := c.GetTransaction("bitcoin", "f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16")
