Using as a library

Links also has a Go client library which you can use, which adds a simple wrapper around an http call, to make shortening links simpler. Download it using the following go get command:

$ go get -u github.com/lrstanley/links/client

View the documentation here

Example

package main

import (
	"fmt"
	"log"

	links "github.com/lrstanley/links/client"
)

func main() {
	uri, err := links.Shorten("https://your-long-link.com/longer/link", "", nil)
	if err != nil {
		log.Fatalf("unable to shorten link: %s", err)
	}

	fmt.Printf("shortened: %s\n", uri.String())
}

API

Shortening a link is quite easy. simply send a POST request to https://links.wtf/add, which will return JSON-safe information as shown below:

$ curl --data "url=http://google.com" https://links.wtf/add
{"url": "https://links.wtf/27f4", "success": true}

Password protection

You can also password protect a link, simply by adding a password variable to the payload:

$ curl --data 'url=https://google.com/example&encrypt=y0urp4$$w0rd' https://links.wtf/add
{"url": "https://links.wtf/abc123", "success": true}
