    - [Documentation](https://ipinfo.io/developers/residential-proxy-api)


    ### Privacy Detection Standard

    Detect VPNs, proxies, Tor exit nodes, relays, and hosting providers associated with an IP address. Returns core privacy signals including service provider identification.

    - Endpoints: `/{ip}/privacy`

    - [Documentation](https://ipinfo.io/developers/privacy-standard-api)


    ### Privacy Detection Extended

    - Endpoints: `/{ip}/privacy_extended`

    - [Documentation](https://ipinfo.io/developers/privacy-extended-api)
