Where do I find the captchaId?

Look for the data-captcha-id attribute on the #lemin-cropped-captcha div, or extract it from the script URL: https://api.leminnow.com/captcha/v1/cropped/{CAPTCHA_ID}/js

Does this support non-cropped Lemin types?

Currently we support the cropped (slider) variant only, which is by far the most common deployment.

Lemin Cropped Captcha Solver

What is Lemin Cropped Captcha?

Lemin Cropped Captcha (leminnow.com) presents a jigsaw-style slider puzzle. A piece is cropped from an image and placed on a slider rail — the user must drag it to the correct position to complete the picture. Used on e-commerce, gaming, and financial sites. The captcha produces a lemin_answer + lemin_challenge_id pair that the site validates server-side.

How It Works

Send Task

POST your LeminTaskProxyLess with the target URL and sitekey to our API. We'll queue it instantly.

We Solve

Capzy's proprietary solver returns the Lemin solution payload (answer + challenge_id) ready for direct submission. Designed for authorized testing and automation.

Get Token

Poll getTaskResult — when status is 'ready', the solution contains the token to inject into the target page.

Quick Integration

solve.py

import requests, time

API = "https://api.capzy.ai"
KEY = "capzy_your_key_here"

# Step 1: Create task
task = requests.post(f"{API}/createTask", json={
    "clientKey": KEY,
    "task": {
        "type": "LeminTaskProxyLess",
        "captchaId": "CROPPED_313061f_ea6d320788434680aa852441fbe30963",
        "websiteURL": "https://example.com/login"
    }
}).json()

task_id = task["taskId"]
print(f"Task created: {task_id}")

# Step 2: Poll for result
while True:
    result = requests.post(f"{API}/getTaskResult", json={
        "clientKey": KEY,
        "taskId": task_id
    }).json()

    if result["status"] == "ready":
        print("Solved!", result["solution"])
        break
    elif result["status"] == "failed":
        print("Failed:", result.get("errorDescription"))
        break

    time.sleep(1)

Using Your Own Proxy

Use LeminTask instead of LeminTaskProxyLess to route the solve through your own proxy. This is useful when the target site checks the IP that solved the captcha matches the IP submitting the form.

solve_proxy.py

import requests, time

API = "https://api.capzy.ai"
KEY = "capzy_your_key_here"

# Step 1: Create task
task = requests.post(f"{API}/createTask", json={
    "clientKey": KEY,
    "task": {
        "type": "LeminTask",
        "captchaId": "CROPPED_313061f_ea6d320788434680aa852441fbe30963",
        "proxyPort": "8080",
        "proxyType": "http",
        "proxyLogin": "user",
        "websiteURL": "https://example.com/login",
        "proxyAddress": "123.45.67.89",
        "proxyPassword": "pass"
    }
}).json()

task_id = task["taskId"]
print(f"Task created: {task_id}")

# Step 2: Poll for result
while True:
    result = requests.post(f"{API}/getTaskResult", json={
        "clientKey": KEY,
        "taskId": task_id
    }).json()

    if result["status"] == "ready":
        print("Solved!", result["solution"])
        break
    elif result["status"] == "failed":
        print("Failed:", result.get("errorDescription"))
        break

    time.sleep(1)
