Features

• ⚡ Multi-Captcha Support — Cloudflare Turnstile, Google reCAPTCHA v2 / v3, Arkose FunCaptcha, GeeTest v3, normal image captchas, and text questions.
• 🔄 Built-in Auto Polling — High-level methods like solve_turnstile() and solve_recaptcha_v2() automatically poll until resolved.
• 🐍 Modern Pythonic Design — Type annotations, dataclasses, context manager support (with SolveCaptchaClient(...) as client:), and custom exceptions.
• 🛠️ Asynchronous Task Queue — Low-level create_task() and get_task_result() for custom background queue workers.
• ⚖️ Accuracy Reports — report_good() and report_bad() for solving quality feedback and automated credit refunds.

Installation

pip install solvecaptcha

Requires Python 3.10 or higher.

Quick Start (Safe Check)

The quick check only queries your account balance. It does not create tasks or consume credits.

import os
from solvecaptcha import SolveCaptchaClient

client = SolveCaptchaClient(api_key=os.environ["SOLVECAPTCHA_API_KEY"])

balance = client.get_balance()
print(f"Current SolveCaptcha balance: ${balance:.4f} USD")

Usage Guide

1. Solving Cloudflare Turnstile

Solve Cloudflare Turnstile challenges and retrieve the verification token:

from solvecaptcha import SolveCaptchaClient

with SolveCaptchaClient(api_key="your_api_key") as client:
    token = client.solve_turnstile(
        sitekey="0x4AAAAAAADnPIDROrmt1Wwj",
        pageurl="https://example.com/protected",
        action="login",  # optional
    )
    print("Turnstile token:", token)

2. Solving Google reCAPTCHA v2 & v3

Solve checkbox or invisible reCAPTCHA v2, or score-based reCAPTCHA v3:

with SolveCaptchaClient(api_key="your_api_key") as client:
    # reCAPTCHA v2
    token_v2 = client.solve_recaptcha_v2(
        googlekey="6Le-wvkSAAAAAPBMRTvw0Q4CeHg-tUnSQVwyYcxQ",
        pageurl="https://example.com/protected",
        invisible=0,
    )
    print("reCAPTCHA v2 token:", token_v2)

    # reCAPTCHA v3
    token_v3 = client.solve_recaptcha_v3(
        googlekey="6LdyC2cUAAAAABlzY2Hg-tUnSQVwyYcxQ",
        pageurl="https://example.com/checkout",
        action="checkout",
        min_score=0.7,
    )
    print("reCAPTCHA v3 token:", token_v3)

3. Solving Normal Image CAPTCHA

Solve distorted image captchas by passing a base64-encoded string:

import base64
from solvecaptcha import SolveCaptchaClient

with open("captcha.png", "rb") as f:
    b64_image = base64.b64encode(f.read()).decode("utf-8")

with SolveCaptchaClient(api_key="your_api_key") as client:
    solution_text = client.solve_image(
        body=b64_image,
        numeric=1,  # numbers only
        min_len=4,
        max_len=6,
    )
    print("Solved captcha text:", solution_text)

4. Low-Level Task Flow

For asynchronous background tasks or task queues:

import time
from solvecaptcha import SolveCaptchaClient

with SolveCaptchaClient(api_key="your_api_key") as client:
    # 1. Create task
    task_id = client.create_task({
        "method": "turnstile",
        "sitekey": "0x4AAAAAAADnPIDROrmt1Wwj",
        "pageurl": "https://example.com",
    })
    print(f"Task submitted: {task_id}")

    # 2. Poll manually or wait
    token = None
    for _ in range(30):
        time.sleep(5)
        token = client.get_task_result(task_id)
        if token:
            break

    if token:
        print("Solved:", token)
        client.report_good(task_id)
    else:
        print("Failed to resolve in time.")

Error Handling

When an API error occurs, SolveCaptchaError is raised:

from solvecaptcha import SolveCaptchaClient, SolveCaptchaError

try:
    with SolveCaptchaClient(api_key="invalid_key") as client:
        client.get_balance()
except SolveCaptchaError as exc:
    print(f"Error Code: {exc.code}")
    print(f"Message: {exc.message}")

Common error codes:

• ERROR_WRONG_USER_KEY — Provided API key is incorrect.
• ERROR_KEY_DOES_NOT_EXIST — Invalid API key.
• ERROR_ZERO_BALANCE — Insufficient funds on account.
• ERROR_NO_SLOT_AVAILABLE — Solving queue currently congested.
• CAPCHA_NOT_READY — Resolution in progress.
• TIMEOUT — Maximum polling wait duration exceeded.
