Authentication

The authentication is done passing your API token associated with your pro plan as x-api-key request header.

The following examples show how to use the Microlink API with CLI, cURL, JavaScript, Python, Ruby, PHP & Golang, targeting 'https://github.com/microlinkhq' URL with 'apiKey' API parameter:

CLI Microlink API example

microlink https://github.com/microlinkhq --api-key YOUR_API_TOKEN

cURL Microlink API example

curl -G "https://api.microlink.io" \
  -H "x-api-key: YOUR_API_TOKEN" \
  -d "url=https://github.com/microlinkhq"

JavaScript Microlink API example

import mql from '@microlink/mql'

const { data } = await mql('https://github.com/microlinkhq', {
  apiKey: "YOUR_API_TOKEN"
})

Python Microlink API example

import requests

url = "https://api.microlink.io/"

querystring = {
    "url": "https://github.com/microlinkhq"
}

headers = {
    "x-api-key": "YOUR_API_TOKEN"
}

response = requests.get(url, params=querystring, headers=headers)

print(response.json())

Ruby Microlink API example

require 'uri'
require 'net/http'

base_url = "https://api.microlink.io/"

params = {
  url: "https://github.com/microlinkhq"
}

uri = URI(base_url)
uri.query = URI.encode_www_form(params)

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true

request = Net::HTTP::Get.new(uri)
request['x-api-key'] = "YOUR_API_TOKEN"
response = http.request(request)

puts response.body

PHP Microlink API example

<?php

$baseUrl = "https://api.microlink.io/";

$params = [
    "url" => "https://github.com/microlinkhq"
];

$query = http_build_query($params);
$url = $baseUrl . '?' . $query;

$curl = curl_init();

curl_setopt_array($curl, [
    CURLOPT_URL => $url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => [
        "x-api-key: YOUR_API_TOKEN"
    ]
]);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
    echo "cURL Error #: " . $err;
} else {
    echo $response;
}

Golang Microlink API example

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "io"
)

func main() {
    baseURL := "https://api.microlink.io"

    u, err := url.Parse(baseURL)
    if err != nil {
        panic(err)
    }
    q := u.Query()
    q.Set("url", "https://github.com/microlinkhq")
    u.RawQuery = q.Encode()

    req, err := http.NewRequest("GET", u.String(), nil)
    if err != nil {
        panic(err)
    }

    req.Header.Set("x-api-key", "YOUR_API_TOKEN")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    body, err := io.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }

    fmt.Println(string(body))
}
You can ensure your authentication is done correctly checking the x-pricing-plan header on the response.
content-type    : application/json; charset=utf-8
x-response-time : 1.7s
x-pricing-plan  : pro
x-cache-ttl     : 86400000
x-request-id    : iad:2eb66538-0a16-4c56-b613-511d99507c9f
x-cache-status  : BYPASS
cache-control   : public, must-revalidate, max-age=0
x-fetch-time    : 0ms
If you need to consume the API from a frontend side (e.g, from a website), don't attach your API token directly in your client code: It will easy to a visitor leak it and consume your API quota without consent.
Instead, you need to setup a mechanism to just allow consume your token for a allowed list of trusted domains.
Check our repositories and to accomplish that, only allowing a list of well-known domains to consume your API quota.
