Feature Comparison

API Comparison

CaptchaAI (2Captcha-compatible)

import requests
import time

# Simple, well-documented API
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"]

# Standard polling
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,
    })
    if result.json()["request"] != "CAPCHA_NOT_READY":
        token = result.json()["request"]
        break

NextCaptcha

# NextCaptcha uses custom JSON format
resp = requests.post("https://api.nextcaptcha.com/createTask", json={
    "clientKey": "YOUR_API_KEY",
    "task": {
        "type": "RecaptchaV2TaskProxyless",
        "websiteURL": "https://example.com",
        "websiteKey": "SITE_KEY",
    },
})
task_id = resp.json()["taskId"]

for _ in range(60):
    time.sleep(5)
    result = requests.post("https://api.nextcaptcha.com/getTaskResult", json={
        "clientKey": "YOUR_API_KEY",
        "taskId": task_id,
    })
    if result.json()["status"] == "ready":
        token = result.json()["solution"]["gRecaptchaResponse"]
        break

CaptchaAI advantage: 2Captcha-compatible API means existing 2Captcha integrations work with a simple domain swap. NextCaptcha requires rewriting API calls.

Success Rate Comparison

Solve Speed

Pricing

CaptchaAI uses thread-based plans with unlimited solves per thread per month, starting at $15/month. NextCaptcha uses per-solve pricing. The table below shows CaptchaAI's effective per-1K cost at typical thread utilization next to NextCaptcha's published rates.

Pricing at scale

NextCaptcha bills per solve, so 10× the traffic = 10× the bill. CaptchaAI bills the thread — every CAPTCHA cleared on a running thread is free, so the effective per-1K cost falls as utilization rises. Using NextCaptcha's reCAPTCHA v2 rate (~$1.20 / 1,000 solves) against CaptchaAI plans sized to peak concurrency:

Above ~15K solves/month the thread-based model is structurally cheaper than NextCaptcha's per-solve billing, and the gap widens at every step.
