Captcha Solver API JavaScript Examples

A collection of examples for interacting with the Captcha Solver service using Node.js.

This project demonstrates how to send HTTP requests to the API for solving CAPTCHA challenges. You will find examples for reCAPTCHA v2, reCAPTCHA v3, and Cloudflare Turnstile. The code helps automate task creation, status polling, and result retrieval.

Quick Start

Use your API key to access service methods.

Example request structure for solving reCAPTCHA v2:

const axios = require('axios');

const response = await axios.post("https://api.captcha-solver.com/createTask", {
    "clientKey": "YOUR_API_KEY",
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": "https://example.com/login",
        "websiteKey": "6Le-xxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    }
});

const taskId = response.data.taskId;
