Rotasi API Key CaptchaAI: Manajemen Multi-Kunci

Menjalankan semua traffic melalui satu API key menciptakan satu titik kegagalan. Jika key kehabisan saldo, mencapai rate limit, atau dinonaktifkan, seluruh pipeline Anda akan berhenti. Rotasi key mendistribusikan beban ke beberapa key dan menyediakan failover otomatis.

Rotasi Round-Robin

Strategi paling sederhana — menelusuri key secara merata:

Python

import itertools
import requests

API_KEYS = [
    "KEY_ACCOUNT_1",
    "KEY_ACCOUNT_2",
    "KEY_ACCOUNT_3",
]

key_cycle = itertools.cycle(API_KEYS)


def get_next_key():
    return next(key_cycle)


def solve_captcha(sitekey, page_url):
    api_key = get_next_key()
    resp = requests.post("https://ocr.captchaai.com/in.php", data={
        "key": api_key,
        "method": "userrecaptcha",
        "googlekey": sitekey,
        "pageurl": page_url,
        "json": "1",
    })
    data = resp.json()
    if data["status"] != 1:
        raise Exception(f"[{api_key[:8]}...] {data['request']}")

    print(f"Submitted with key {api_key[:8]}...")
    return data["request"], api_key


task_id, used_key = solve_captcha("6Le-SITEKEY", "https://example.com")

Rotasi Tertimbang dengan Balance-Awareness

Arahkan lebih banyak traffic ke key dengan saldo lebih tinggi:

import random
import requests
import threading

SUBMIT_URL = "https://ocr.captchaai.com/in.php"
RESULT_URL = "https://ocr.captchaai.com/res.php"


class KeyRotator:
    def __init__(self, keys):
        self.keys = {k: {"balance": 0, "failures": 0, "disabled": False} for k in keys}
        self._lock = threading.Lock()
        self.refresh_balances()

    def refresh_balances(self):
        for key in self.keys:
            try:
                resp = requests.get(RESULT_URL, params={
                    "key": key, "action": "getbalance", "json": "1"
                }, timeout=10).json()
                if resp["status"] == 1:
                    self.keys[key]["balance"] = float(resp["request"])
                    self.keys[key]["disabled"] = False
                else:
                    self.keys[key]["disabled"] = True
            except Exception:
                self.keys[key]["disabled"] = True

    def get_key(self):
        with self._lock:
            available = {
                k: v for k, v in self.keys.items()
                if not v["disabled"] and v["balance"] > 0.01
            }
            if not available:
                raise Exception("No API keys with balance available")

            # Weighted random by balance
            keys = list(available.keys())
            weights = [available[k]["balance"] for k in keys]
            return random.choices(keys, weights=weights, k=1)[0]

    def report_failure(self, key, error_code):
        with self._lock:
            self.keys[key]["failures"] += 1
            if error_code in ("ERROR_WRONG_USER_KEY", "ERROR_KEY_DOES_NOT_EXIST",
                              "ERROR_ZERO_BALANCE", "ERROR_IP_NOT_ALLOWED"):
                self.keys[key]["disabled"] = True
                print(f"[rotator] Disabled key {key[:8]}...: {error_code}")

    def report_success(self, key, cost=0.003):
        with self._lock:
            self.keys[key]["balance"] -= cost
            self.keys[key]["failures"] = 0


rotator = KeyRotator(["KEY_1", "KEY_2", "KEY_3"])

# Usage
api_key = rotator.get_key()
# ... solve captcha ...
rotator.report_success(api_key)

Rotasi dengan Failover

Coba key berikutnya saat salah satu gagal:

Python

def solve_with_failover(sitekey, page_url, max_attempts=3):
    for attempt in range(max_attempts):
        api_key = rotator.get_key()
        try:
            resp = requests.post(SUBMIT_URL, data={
                "key": api_key,
                "method": "userrecaptcha",
                "googlekey": sitekey,
                "pageurl": page_url,
                "json": "1",
            }, timeout=15)
            data = resp.json()

            if data["status"] != 1:
                rotator.report_failure(api_key, data["request"])
                continue

            rotator.report_success(api_key)
            return data["request"], api_key

        except requests.RequestException:
            rotator.report_failure(api_key, "NETWORK_ERROR")
            continue

    raise Exception(f"All {max_attempts} keys failed")

JavaScript

const axios = require('axios');

class KeyRotator {
  constructor(keys) {
    this.keys = keys.map(k => ({ key: k, disabled: false, failures: 0 }));
    this.index = 0;
  }

  getKey() {
    const available = this.keys.filter(k => !k.disabled);
    if (available.length === 0) throw new Error('No API keys available');
    const entry = available[this.index % available.length];
    this.index++;
    return entry.key;
  }

  disable(key, reason) {
    const entry = this.keys.find(k => k.key === key);
    if (entry) {
      entry.disabled = true;
      console.log(`[rotator] Disabled ${key.substring(0, 8)}...: ${reason}`);
    }
  }
}

const rotator = new KeyRotator(['KEY_1', 'KEY_2', 'KEY_3']);

async function solveWithFailover(sitekey, pageurl, maxAttempts = 3) {
  for (let i = 0; i < maxAttempts; i++) {
    const apiKey = rotator.getKey();
    try {
      const resp = await axios.post('https://ocr.captchaai.com/in.php', null, {
        params: { key: apiKey, method: 'userrecaptcha', googlekey: sitekey, pageurl, json: 1 }
      });
      if (resp.data.status !== 1) {
        rotator.disable(apiKey, resp.data.request);
        continue;
      }
      return { taskId: resp.data.request, apiKey };
    } catch (err) {
      rotator.disable(apiKey, 'NETWORK_ERROR');
    }
  }
  throw new Error('All keys failed');
}

Memuat Key dari Environment Variable

Jangan pernah hardcode API key. Muat dari environment:

import os

API_KEYS = os.environ["CAPTCHAAI_KEYS"].split(",")
# Set: CAPTCHAAI_KEYS=key1,key2,key3
rotator = KeyRotator(API_KEYS)

const API_KEYS = process.env.CAPTCHAAI_KEYS.split(',');
const rotator = new KeyRotator(API_KEYS);

Refresh Saldo Terjadwal

Untuk proses long-running, perbarui saldo secara berkala:

import threading

def periodic_refresh(rotator, interval=300):
    def refresh():
        while True:
            rotator.refresh_balances()
            for key, info in rotator.keys.items():
                print(f"  {key[:8]}...: ${info['balance']:.2f} "
                      f"{'(disabled)' if info['disabled'] else '(active)'}")
            threading.Event().wait(interval)

    t = threading.Thread(target=refresh, daemon=True)
    t.start()

periodic_refresh(rotator, interval=300)  # every 5 minutes

Pemecahan Masalah

Pertanyaan Umum

Berapa banyak API key yang harus digunakan?

Dua key menyediakan failover dasar. Tiga key atau lebih memungkinkan load distribution. Untuk operasi volume tinggi (1000+ solve/hari), pertimbangkan 3–5 key.

Bisakah saya menggunakan key dari akun CaptchaAI yang berbeda?

Ya. Setiap key memiliki saldo dan rate limit sendiri. Rotator memprosesnya secara independen.
