-If you want use API you need choice a port where is internal HTTP server will listen for incoming connections. API will not available if miner built without `libmicrohttpd`.
+If you want use HTTP API you need enable it (`"enabled": true,`) then choice `port` and optionaly `host`. API not available if miner built without HTTP support (`-DWITH_HTTP=OFF`).
+
+Offical HTTP client for API: http://workers.xmrig.info/
 
 Example configuration:
 
 ```json
 "api": {
-    "port": 44444,
-    "access-token": "TOKEN",
-    "worker-id": null,
-    "ipv6": false,
-    "restricted": false
+	"id": null,
+	"worker-id": null,
 },
+"http": {
+	"enabled": false,
+	"host": "127.0.0.1",
+	"port": 0,
+	"access-token": null,
+	"restricted": true
+}
 ```
 
-* **port** Port for incoming connections `http://<miner ip>:<port>`.
-* **access-token** [Bearer](https://gist.github.com/xmrig/c75fdd1f8e0f3bac05500be2ab718f8e#file-api-html-L54) access token to secure access to API.
+#### Global API options
+* **id** Miner ID, if not set created automatically.
 * **worker-id** Optional worker name, if not set will be detected automatically.
-* **ipv6** Enable (`true`) or disable (`false`) IPv6 for API.
+
+#### HTTP API options,
+* **enabled** Enable (`true`) or disable (`false`) HTTP API.
+* **host** Host for incoming connections `http://<host>:<port>`, to allow connections from all interfaces use `0.0.0.0` (IPv4) or `::` (IPv4+IPv6).
+* **port** Port for incoming connections `http://<host>:<port>`, zero port is valid option and means random port.
+* **access-token** [Bearer](https://gist.github.com/xmrig/c75fdd1f8e0f3bac05500be2ab718f8e#file-api-html-L54) access token to secure access to API. Miner support this token only via `Authorization` header.
 * **restricted** Use `false` to allow remote configuration.
 
-If you prefer use command line options instead of config file, you can use options: `--api-port`, `--api-access-token`, `--api-worker-id`, `--api-ipv6` and `api-no-restricted`.
