The fastest xCaptcha solver powered by ConvNeXt deep learning. Solve binary image challenges with 97% accuracy in under 1 second. Multi-round support, 2Captcha-compatible API, and the lowest price on the market.
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 ā
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.
Our AI analyzes binary image challenges and identifies which grid cells to click ā all in under 1 second per round
Extract the base64-encoded image from the xCaptcha 3Ć3 grid challenge. Each cell contains a binary classification image (e.g., "Select all images with bicycles").
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.
The API returns buttons_to_click: [1, 5, 8] ā the exact cell indices to click. Simulate clicks and submit. If multi-round, repeat until the token is received.
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)
