Math Captcha Solver, solved in 5.0s.
Send an image of an arithmetic expression (e.g. '3 + 5'), get back the computed answer. Sub-second solves.
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.
Quick Integration
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)
Using the result
# Step 3: Image-to-text / math — submit the recognized text as the captcha answer
answer = result["solution"]["text"]
requests.post("https://target.example.com/login", data={"username": "...", "captcha": answer})1. Send Payload
Dispatch your MathCaptchaTask to our processing cluster via the secure API endpoint.
2. Solving Engine
Capzy's proprietary pipeline reads the expression off the image and returns the computed answer. Fast API path — no proxy, typical solves in ~0.6–1s.
3. Get Result
Poll getTaskResult for the validated token, then finalize your automated request.
