# Supported Protocols **HTTP** ``` 8080 ``` The HTTP protocol is available on port 1338 and is suitable for most scraping tools, browsers, and automation software. This is the recommended option if your application uses standard HTTP-based requests and requires broad compatibility. **SOCKS5** ``` 1080 ``` The SOCKS5 protocol is available on port 1339 and is ideal for applications that require TCP-level tunneling or support non-HTTP traffic. SOCKS5 offers more flexibility for advanced use cases and works with a wide range of software that supports SOCKS-based connections. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
