The interface runs on the same port as the JSON-RPC interface, by default port 9998 for mainnet and port 19998 for testnet. It must be enabled by either starting Dash Core with the `-rest` option or by specifying `rest=1` in the configuration file. Make sure that the RPC interface is also activated. Set `server=1` in `dash.conf` or supply the `-server` argument when starting Dash Core. Starting Dash Core with `dashd` automatically enables the RPC interface. The interface is not intended for public access and is only accessible from localhost by default. {{WARNING}} A web browser can access a HTTP REST interface running on localhost, possibly allowing third parties to use cross-site scripting attacks to download your transaction and block data, reducing your privacy. If you have privacy concerns, you should not run a browser on the same computer as a REST-enabled Dash Core node. The interface uses standard [HTTP status codes](https://en.wikipedia.org/wiki/List_of_HTTP_status_codes) and returns a plain-text description of errors for debugging. {% endautocrossref %}
