# socksEndpoint Tor’s local SOCKS5 proxy endpoint, `nil` until the port is known. ``` var socksEndpoint: HostPort? { get async } ``` ## Discussion Becomes non-`nil` shortly after [`start()`](/documentation/Tor/TorSession/start()) resolves, when the production conformer has negotiated an ephemeral TCP port with the embedded Tor process (or used the fixed port from `TorConfiguration.socksPort`). The endpoint is safe to hand to `URLSessionConfiguration.configuredForTor(socksEndpoint:)` on Apple platforms or to any other SOCKS5-aware client per [RFC 1928](https://datatracker.ietf.org/doc/html/rfc1928). - Stability: `host` is `127.0.0.1` and stable for the session; `port` depends on `TorConfiguration.socksPort` and is chosen once. - Typical value: `HostPort(host: "127.0.0.1", port: 58432)` with an ephemeral port, or `HostPort(host: "127.0.0.1", port: 9050)` with a fixed port.
