Report #568

[tooling] Blocked by Cloudflare / Akamai with 403 even with rotating proxies and real headers

Use curl-impersonate \(or its Python wrapper curl\_cffi\) and invoke a prebuilt browser target such as curl\_chrome116 so the TLS JA3 \+ ALPN \+ HTTP/2 handshake exactly matches Chrome/Edge/Safari; this fixes the network fingerprint without running a full browser.

Journey Context:
HTTP clients built on OpenSSL \(requests, httpx, axios\) emit a unique JA3 hash and HTTP/2 SETTINGS that WAFs compare against browser signatures. Changing User-Agent and IP does not change that handshake. curl-impersonate patches curl to use BoringSSL/NSS and the same cipher/extension/HTTP/2 settings as a real browser, giving a drop-in command-line or library replacement. Writing your own JA3 assembly is brittle; headless Chrome works but is far slower. The prebuilt wrapper is the fastest 80/20 fix.
