Geetest v4 Solver

A Geetest v4 captcha solver with support for slides, concurrency rate limiting, proof-of-work parallelization, and browser-emulated session caching.

Features

• Browser Emulation: Uses horaa-tls to match Chrome headers, TLS fingerprints, and HTTP/2 settings.
• Multiprocessing PoW: Brute-forces challenge nonces in parallel.
• Session Caching: Thread-local session reuse with a configurable TTL to prevent stale connections.
• Rate Limiting: Concurrency queue limits and sliding-window IP rate limiting.

CLI Usage

Start the solver API:

python api_solver.py --host 0.0.0.0 --port 5000 --threads 4 --queue-limit 4 --ip-rate-limit-max 5 --ip-rate-limit-window 60

Solve via command line:

python -m gtv4 <captcha_id> <risk_type> [proxy]
