go-proxycheck

[]

go-proxucheck is a simple library to check general IP address information and verify if it is a proxy or VPN. It's also possible to check email address for signs of being a disposable.

The lib uses the proxycheck.io API to check the IP address and email address. You can use free tier or perform a registration to get a free API key and enjoy bigger limits.

In plans creationg of a simple web server to perform the checks and return results in XML or JSON.

Usage

Single request for occasional checks. Useful when your app needs to check some info about IP once in a while.

    result, err := validate.CheckIPAddress(context.Background(),
		[]string{"8.8.8.8", "8.8.4.4"},
		validate.IPValidationOptions{
			VPN:      validate.VPNOptionBoth,
			ASN:      validate.ASNOptionActive,
			Currency: validate.CurrencyOptionActive,
			Node:     validate.NodeOptionActive,
			Time:     validate.TimeOptionActive,
			Risk:     validate.RiskOptionFull,
			Port:     validate.PortOptionActive,
			Seen:     validate.SeenOptionActive,
			Days:     "30",
			Tag:      "test",
		})
	if err != nil {
		panic(err)
	}

A validator instance for regurlar checks (e.g. in a web server). Useful when you need to check multiple IPs in a short period of time.

	validator := validate.NewValidator(validate.IPValidationOptions{
		VPN:      validate.VPNOptionBoth,
		ASN:      validate.ASNOptionActive,
		Currency: validate.CurrencyOptionActive,
		Node:     validate.NodeOptionActive,
		Time:     validate.TimeOptionActive,
		Risk:     validate.RiskOptionFull,
		Port:     validate.PortOptionActive,
		Seen:     validate.SeenOptionActive,
		Days:     "30",
		Tag:      "test",
	})

	result, err = validator.CheckIPAddress(context.Background(), []string{"8.8.8.8"})
	if err != nil {
		panic(err)
	}

	log.Printf("%+v", result)

	result, err = validator.CheckIPAddress(context.Background(), []string{"8.8.4.4"})
	if err != nil {
		panic(err)
	}

	log.Printf("%+v", result)
