API Design

CaptchaAI uses a 2Captcha-compatible API, making migration simple if you're coming from 2Captcha:

# CaptchaAI — 2Captcha-compatible API
import requests

# Submit task
resp = requests.post("https://ocr.captchaai.com/in.php", data={
    "key": "YOUR_API_KEY",
    "method": "userrecaptcha",
    "googlekey": "SITE_KEY",
    "pageurl": "https://example.com",
    "json": 1,
})
task_id = resp.json()["request"]

# Poll result
import time
for _ in range(60):
    time.sleep(5)
    result = requests.get("https://ocr.captchaai.com/res.php", params={
        "key": "YOUR_API_KEY",
        "action": "get",
        "id": task_id,
        "json": 1,
    })
    data = result.json()
    if data["request"] != "CAPCHA_NOT_READY":
        print(f"Token: {data['request']}")
        break

# CapMonster Cloud — Custom API
resp = requests.post("https://api.capmonster.cloud/createTask", json={
    "clientKey": "YOUR_API_KEY",
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": "https://example.com",
        "websiteKey": "SITE_KEY",
    },
})
task_id = resp.json()["taskId"]

# Poll result
for _ in range(60):
    time.sleep(5)
    result = requests.post("https://api.capmonster.cloud/getTaskResult", json={
        "clientKey": "YOUR_API_KEY",
        "taskId": task_id,
    })
    data = result.json()
    if data["status"] == "ready":
        print(f"Token: {data['solution']['gRecaptchaResponse']}")
        break

Key API difference: CaptchaAI's 2Captcha-compatible format means you can switch from 2Captcha by changing only the domain. CapMonster uses a different request/response format.
