What is it?

Triocoder Account is simple to use URL availibility checker. It tells you wheater url is available or not.


On this page you'll learn how to create request to use our API. To get started your account must be eligible to use our Triocoder Cloud API.

How does it work?


When you send a request our server checks your API Key. It finds it in the database and increase your usage by 1. It also helps us limit usage for monetised APIs.

You can view your api keys here


Our server gets URL from your request. With help of HTTP Headers it checks if URL is online.



Communication between server and client is handled by JSON!


JSON request is sent to server (

Request Example
{"key":"YOUR_API_KEY", "url":""}

First element in JSON named KEY is where you put your API key accessible on Developer Console.

Second element in JSON named URL is where you put URL address that you want to check.


There are 3 valid responses that server can output you.

First Response
{success: "no", msg: "Key not found."}

Element SUCCESS was NO, which means that your request was not successful. The reason is described in element MSG.

Second Response
{success: "yes", urlOnline:false, msg: "Url offline."}

Element SUCCESS was YES, which means that your request was successful. However, element URLONLINE suggests that the URL was not online.

Third Response
{success: "yes", urlOnline:true, msg: "Url online."}

Element SUCCESS was YES, which means that your request was successful. Element URLONLINE suggests that the URL was online.

Useful Tip:

It is recomended to use libraries to perform API requests. In our Java example library BSON is used to construct JSON for request. After that libraries OkHTTP and Okio are used to perform HTTP request.

Java Code Example
package com.your.package;

import org.bson.Document;
import okhttp3.Call;
import okhttp3.FormBody;
import okhttp3.MediaType;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class Main {

    public static void main(String[] args) {
        //create new BSON document
        Document jsonToSend = new Document();
        /*ADD ITEMS TO JSON*/
        //Your API key
        jsonToSend.append("key", "YOUR_API_KEY");
        //Url that you want to check
        jsonToSend.append("url", "");
        //Convert BSON document to String
        String sendRaw = jsonToSend.toJson();
        //Declare and create client
        OkHttpClient client = new OkHttpClient();
        //Create request body
        RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=UTF-8"), sendRaw);
        Request request = new Request.Builder()
        Call call = client.newCall(request);

        call.enqueue(new okhttp3.Callback() {
            public void onFailure(Call call, IOException e) {
                //Request failed, output exeption
                System.out.println("FAIL: " + e.getMessage());

            public void onResponse(Call call, Response response) throws IOException {
                //request successfull
                String serverResponse = response.body().string();
                //output server response
