What is Math Captcha?

A math captcha is an image showing a small arithmetic expression — addition, subtraction, multiplication, or division of two or three small whole numbers (e.g. '7 + 2', 'twelve minus four', '6 × 3'). The user is expected to compute the result and type the numeric answer.

How It Works

1

Send Task

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

2

We Solve

Capzy's proprietary vision pipeline reads the expression off the image and computes the answer in a sandboxed evaluator. Pure API path — no browser, no proxy, typical solves in ~0.6–1s.

3

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": "MathCaptchaTask",
        "body": "/9j/4AAQSkZJRgABAQ..."
    }
}).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)
