Installation

Add the library to your go.mod:

module main

go 1.22.1

require (
    github.com/greipio/go v1.0.0
)

Then, download the Greip library by running:

go mod download github.com/greipio/go

Usage

To use the Greip library, first import the package and initialize the Greip instance with your API token. Here’s a basic example:

package main

import (
    "fmt"
    "github.com/greipio/go"
)

func main() {
    // Initialize the Greip instance with your API token
    greipInstance := greip.NewGreip("YOUR_API_TOKEN")

    // Example: Lookup IP information
    response, err := greipInstance.Lookup("1.1.1.1", []string{"device", "security"})
    if err != nil {
        fmt.Println("Error:", err)
        return
    }
    fmt.Println(response.IP, response.ContinentName, response.City)
}

Methods

The Greip library provides various methods to interact with the API:

• Lookup(ip string, params []string, lang ...string): Get geolocation information about an IP address.
• Threats(ip string): Get threat intelligence related to an IP address.
• BulkLookup(ips []string, params []string, lang ...string): Get geolocation information for multiple IP addresses.
• Country(countryCode string, params []string, lang ...string): Get information about a country by its code.
• Profanity(text string): Check if a given text contains profanity.
• ASN(asn string): Get information about an ASN (Autonomous System Number).
• Email(email string): Validate an email address.
• Phone(phone string, countryCode string): Validate or lookup a phone number.
• IBAN(iban string): Validate or lookup an IBAN number.
• Payment(data map[string]interface{}): Check if a payment transaction is fraudulent.

Example of Method Usage

// Lookup country information
countryInfo, err := greipInstance.Country("US")
if err != nil {
    fmt.Println("Error:", err)
    return
}
fmt.Println(countryInfo.CountryName, countryInfo.Population)

Development Mode

If you need to test the integration without affecting your subscription usage, you can set the test attribute to true when initializing the Greip instance:

greipInstance := greip.NewGreip("YOUR_API_TOKEN", true)

Warning

Enabling the test mode returns fake data. Do not use it in production.

Error Handling

The library returns error for invalid parameters and request-related issues. Here’s an example of handling errors:

response, err := greipInstance.Lookup("INVALID_IP", nil)
if err != nil {
    fmt.Println("Error:", err)
    return
}
fmt.Println(response)
