I've tested it against YouTube, Twitch, Ticketmaster, and Yahoo Finance. It will detect any transport like JSON, WebSocket, GraphQL, SSE, Protbuf, UDP, WebRTC, ect.. It after 3 hours and some coaching succeeded in reverse engineering ChatGPT + Cloudflare Turnstile but I didn't merge that into it yet.
It works by Claude using the Chrome DevTools Protocol (CDP) intercepting all traffic.
