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
