## What it is
A Python toolkit that reverse-engineers and replays the end-to-end ChatGPT Plus/Team/Pro subscription payment flow (Stripe Checkout, PayPal/GoPay/QRIS, OAuth+PKCE), including a from-scratch hCaptcha visual solver built on VLMs with CLIP/OpenCV fallbacks. It also ships empirical anti-fraud research data and is explicitly scoped for CTF, authorized bug bounty, and security research on owned systems.

## Use cases
- solve hcaptcha challenges automatically with a vision model
- replay chatgpt subscription payment protocol for security research
- study anti-fraud detection mechanisms empirically
- authorized bug bounty testing of payment flows
- ctf challenges involving captcha and payment systems
- reverse engineer stripe checkout and paypal billing agreement flows

## When to choose
- you need an independent, self-hosted hCaptcha solver with VLM and heuristic fallbacks
- you are doing authorized security research or bug bounty on payment/subscription flows
- you want empirical data on anti-fraud mechanisms like IP fingerprinting and batch bans
- you need a protocol-level client for the ChatGPT subscription chain in a lab setting

## When to avoid
- you intend to bypass payments, create bulk accounts, or resell subscriptions - this is prohibited and illegal
- you need a production payment integration - use official Stripe/PayPal SDKs instead
- you want a turnkey ChatGPT subscription service rather than a research toolkit
- you cannot operate within legal boundaries of authorized targets only
