WebUI Setup Wizard (Recommended for First-Time Setup)

Reduces ~3 hour manual config to ~15 minutes. Generates both config files automatically.

# Install backend deps
pip install -r webui/requirements.txt

# Build frontend (one-time)
cd webui/frontend && pnpm i && pnpm build && cd ../..

# Start wizard
python -m webui.server
# Open http://127.0.0.1:8765 — redirects to /setup on first visit

Features:

• 14-step configuration wizard
• Real-time preflight self-checks
• SSE log streaming for live pipeline monitoring
• Generates CTF-pay/config.auto.json + CTF-reg/config.paypal-proxy.json

For public access via nginx reverse proxy, see webui/README.md.

hCaptcha Solver — Standalone Usage

The solver (CTF-pay/hcaptcha_auto_solver.py) is independently usable with a 3-layer decision architecture:

1. VLM primary path — OpenAI-compatible vision model identifies challenge targets
2. CLIP/OpenCV heuristic fallback — local model, no API needed
3. Human action synthesis — Playwright realistic mouse movement

Basic usage

import asyncio
from CTF-pay.hcaptcha_auto_solver import HCaptchaSolver

async def solve_captcha(page):
    solver = HCaptchaSolver(
        page=page,
        vlm_api_key=os.environ["VLM_API_KEY"],
        vlm_base_url=os.environ["VLM_BASE_URL"],
        vlm_model="gpt-4o",
        clip_venv_path=os.path.expanduser("~/.venvs/ctfml"),
        debug=True
    )
    result = await solver.solve()
    return result  # True if solved, False if failed

asyncio.run(solve_captcha(page))

With Playwright + Camoufox

import asyncio
from camoufox.async_api import AsyncCamoufox
from CTF_pay.hcaptcha_auto_solver import HCaptchaSolver

async def main():
    async with AsyncCamoufox(headless=True, humanize=True) as browser:
        page = await browser.new_page()
        await page.goto("https://example.com/page-with-hcaptcha")
        
        solver = HCaptchaSolver(
            page=page,
            vlm_api_key=os.environ["VLM_API_KEY"],
            vlm_base_url=os.environ.get("VLM_BASE_URL", "https://api.openai.com/v1"),
            vlm_model="gpt-4o",
        )
        
        success = await solver.solve()
        if success:
            print("hCaptcha solved successfully")
        else:
            print("Solver failed, check logs")

asyncio.run(main())

Supported challenge types (12)

• Image classification (single/multi-select)
• Bounding box / area selection
• Drag-and-drop alignment
• 3D object rotation
• Text-in-image matching
• Spatial relationship challenges
• Count-based selection
• Sequential ordering
• Color/pattern matching
• Object pair matching
• Scene classification
• Entity attribute verification

CLIP-only mode (no VLM API)

solver = HCaptchaSolver(
    page=page,
    vlm_api_key=None,          # Disables VLM primary path
    clip_venv_path=os.path.expanduser("~/.venvs/ctfml"),
    fallback_only=True
)

Daemon Mode — 12-Self-Healing Branches

pipeline.py::daemon() handles these failure conditions automatically:

Branch	Trigger	Recovery
IP rotation	Ban detected / probe fail	Webshare API fetch new IP
CF DNS quota	Zone record limit hit	Clean stale catch-all records
tmpfs orphan	Crashed browser profile left	Reclaim tmpfs mounts
gost relay	Relay process died	Restart watchdog
DataDome slider	Slider CAPTCHA on registration	Auto-drag synthesis
PayPal 2FA	Session expired	Re-authenticate flow
Stripe fingerprint	runtime.version drift	Re-align JS checksum
Batch correlation	Mass ban detected	Pause + stagger restart
DNS propagation	New subdomain not resolving	Poll + retry with backoff
OAuth PKCE	Token exchange failure	Regenerate challenge
Account approval	Manual approval queue	Poll /approve endpoint
Memory pressure	Browser OOM	Graceful restart with GC

Anti-Fraud Research Data

Key empirical findings from docs/anti-fraud-research.md:

• 24-hour survival rate: ~2% across 45 test accounts
• Mechanism: Batch correlation — accounts registered in same IP/time window get delayed mass ban
• Probe vs ban layer separation: Initial probe passes, ban fires 6–18 hours later
• IP fingerprinting: String-level exact match, not subnet-level

# Access research data programmatically
import json

with open("docs/anti-fraud-research.md") as f:
    # Raw markdown with embedded JSON samples
    content = f.read()

# Survival curve model (from research):
# P(survival at t hours) ≈ 0.85 * exp(-0.31 * t) for batch size > 5
# P(survival at t hours) ≈ 0.60 * exp(-0.08 * t) for batch size == 1

Protocol Chain — Key Endpoints

Documented from packet capture (mitmproxy intercept):

POST https://checkout.stripe.com/pay/{session_id}
  → Stripe payment intent confirm

POST https://api.openai.com/dashboard/billing/stripe/confirm
  → ChatGPT billing linkage

GET  https://api.openai.com/dashboard/billing/subscription/approve?token={t}
  → Manual approval poll

POST https://www.paypal.com/agreements/approve
  → PayPal billing agreement

GET  https://auth.openai.com/authorize
  → Codex OAuth + PKCE initiation

POST https://auth.openai.com/oauth/token
  → refresh_token exchange

Stripe Runtime Fingerprint Maintenance

card.py embeds Stripe JS runtime fingerprints that drift every few weeks:

# In CTF-pay/card.py — fields to re-align after Stripe updates:
STRIPE_RUNTIME = {
    "runtime_version": "5.104.0",   # Check stripe.js version
    "js_checksum": "sha256-...",     # Recompute from live stripe.js
    "rv_timestamp": 1714000000,      # Update to current epoch
}

# To re-capture current values:
# 1. Open browser devtools on any Stripe Checkout page
# 2. Network tab → filter "stripe" → find runtime init request
# 3. Extract from request payload or JS source

---

Debugging

Common failures

PayPal OTP loop — First run requires manual 2FA:

# Run without --daemon first, complete OTP manually
xvfb-run -a python pipeline.py --config CTF-pay/config.paypal.json --paypal --interactive

hCaptcha VLM timeout — VLM API unreachable:

# Test VLM connectivity
python -c "
import openai, os
client = openai.OpenAI(api_key=os.environ['VLM_API_KEY'], base_url=os.environ.get('VLM_BASE_URL'))
print(client.models.list())
"

Stripe fingerprint mismatch — Protocol drift:

# Check card.py STRIPE_RUNTIME block, compare to live stripe.js
# Use mitmproxy to capture fresh values:
mitmproxy --mode upstream:http://your-proxy:1080 -s CTF-pay/capture_stripe.py

CF DNS quota exceeded:

# Manual cleanup
python -c "
import requests, os
headers = {'Authorization': f'Bearer {os.environ[\"CF_API_TOKEN\"]}'}
r = requests.get(f'https://api.cloudflare.com/client/v4/zones/{os.environ[\"CF_ZONE_ID\"]}/dns_records?per_page=100', headers=headers)
print(f'Record count: {len(r.json()[\"result\"])}')
"

Camoufox not found:

camoufox fetch
python -c "from camoufox.async_api import AsyncCamoufox; print('OK')"

Contributing

Priority contributions (by impact):

1. New hCaptcha challenge type solvers — provide round.json with challenge data + solution
2. Protocol adaptations when Stripe/PayPal/OpenAI break — include packet capture diff
3. New daemon self-healing branches — include trigger log + recovery log
4. Anti-fraud empirical data — follow anonymization pattern in existing research doc

PR requirements (no evidence = auto-close):

• Solver PRs: round.json with challenge rounds
• Protocol PRs: packet capture before/after comparison
• Daemon PRs: trigger log + successful recovery log
