To start working with censys you have to create an account and get an application Key and application secret First. You can do this at https://censys.io.

Download the package:

go get github.com/oucema001/censys-go

You can now use the library in your own projects :-)

package main

import (
    "log"
    
    "github.com/oucema001/censys-go"
)

func main() {
    client := censys.NewClient(nil, "MY_APPID", "MY_APPSECRET")
    dns, err := client.GetDNSResolve([]string{"google.com", "ya.ru"})
    
    a, err := client.Search(context.Background(), "www.google.com", censys.WEBSITES)
	if err != nil {
		log.Panic(err)
    } else {
        fmt.Println("alexa rank : %d",a.Results[0].AlexaRank)
    }
}

This will output :

alexa rank : 1
