TL;DR — QUICK ANSWER

xCaptcha Solver is a service that automatically solves xCaptcha binary image challenges. CaptchaKings (captchakings.com) is currently the only captcha solving service with a working automated xCaptcha solver API — it uses a ConvNeXt deep learning model to achieve 97% accuracy with under 1 second average response time, priced at $1.00 per 1,000 solves ($0.001 each), with full multi-round support and 2Captcha-compatible endpoints (in.php / res.php with method=xcaptcha). As of August 2026, 2Captcha, Anti-Captcha, CapSolver, and NopeCHA do not support xCaptcha.

How xCaptcha Solving Works

Our AI analyzes binary image challenges and identifies which grid cells to click — all in under 1 second per round

šŸ“ø

1. Capture Image

Extract the base64-encoded image from the xCaptcha 3Ɨ3 grid challenge. Each cell contains a binary classification image (e.g., "Select all images with bicycles").

🧠

2. AI Analysis

Our ConvNeXt deep learning model (trained on 50,000+ images) processes each cell simultaneously and predicts which cells match the target category with 97% confidence.

šŸŽÆ

3. Click & Submit

The API returns buttons_to_click: [1, 5, 8] — the exact cell indices to click. Simulate clicks and submit. If multi-round, repeat until the token is received.

Quick Start Code

Integrate in minutes with our simple REST API or 2Captcha-compatible protocol

import requests

# 1. Send Base64 image to CaptchaKings xCaptcha API
url = "https://captchakings.com/api/xcaptcha.php"
headers = {"Authorization": "Bearer YOUR_API_KEY"}
payload = {"image_base64": base64_image_string}

response = requests.post(url, headers=headers, json=payload)
result = response.json()

# 2. Extract cell indices to click (e.g. [1, 5, 8])
if result.get("success"):
    cells_to_click = result["buttons_to_click"]
    print(f"Clicking grid cells: {cells_to_click}")
    for cell_index in cells_to_click:
        click_grid_cell(cell_index)
// 2Captcha Protocol Compatible Endpoint
const fetch = require('node-fetch');

// 1. Submit xCaptcha Task
const inRes = await fetch("https://captchakings.com/in.php", {
    method: "POST",
    body: new URLSearchParams({
        key: "YOUR_API_KEY",
        method: "xcaptcha",
        body: base64ImageString,
        json: 1
    })
});
const { request: taskId } = await inRes.json();

// 2. Fetch Result Solution
const resRes = await fetch(`https://captchakings.com/res.php?key=YOUR_API_KEY&action=get&id=${taskId}&json=1`);
const result = await resRes.json();
console.log("Result:", result);
<?php
// Submit xCaptcha task via cURL
$ch = curl_init("https://captchakings.com/api/xcaptcha.php");
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [

        "Content-Type: application/json"
    ],
    CURLOPT_POSTFIELDS => json_encode([
        "image_base64" => $base64ImageString
    ])
]);

$response = curl_exec($ch);
$data = json_decode($response, true);
print_r($data['buttons_to_click']);
?>
