TLS fingerprinting

Some services detect and block Node.js TLS fingerprints. Use --tls-provider utls to spoof a browser fingerprint:

Available fingerprints: chrome120, chrome102, chrome100, firefox120, firefox105, firefox102, safari16, edge106, edge85, ios14, android11, electron, randomized, golanghttp2

Security
Warning: Disabling certificate verification (NODE_TLS_REJECT_UNAUTHORIZED=0, --ignore-certificate-errors, -k) exposes traffic between the app and the proxy to MITM attacks. For AI agents, this means potential RCE on your machine. Only do this on trusted networks.
To avoid disabling verification, use -c ./certs to persist the CA certificate and trust it in your OS/app instead.
