Standard Python `requests` and `urllib3` use OpenSSL with a default cipher list that Cloudflare, Akamai, and DataDome block on the very first TLS `ClientHello` packet before your HTTP headers are even decrypted! ```python from curl_cffi import requests resp = requests.get( 'https://protected-target.com', impersonate='chrome124', proxies={'https': 'socks5://127.0.0.1:1080'} ) print(resp.status_code) ``` `curl_cffi` uses `curl-impersonate` compiled with Chrome's BoringSSL and matches Chrome's JA3, JA4, and HTTP/2 ALPN frames 100%.
