 ## Endpoints
 
-### GET /1/summary
+### APIVersion 2
 
-Get miner summary information. [Example](api/1/summary.json).
+#### GET /2/summary
 
-### GET /1/threads
+Get miner summary information. [Example](api/2/summary.json).
 
-Get detailed information about miner threads. [Example](api/1/threads.json).
+#### GET /2/backends
+
+Get detailed information about miner backends. [Example](api/2/backends.json).
+
+### APIVersion 1 (deprecated)
+
+#### GET /1/summary
+
+Get miner summary information. Currently identical to `GET /2/summary`
+
+#### GET /1/threads
+
+**REMOVED** Get detailed information about miner threads. [Example](api/1/threads.json).
+
+Functionally replaced by `GET /2/backends` which contains a `threads` item per backend.

 ## Restricted endpoints
 
 All API endpoints below allow access to sensitive information and remote configure miner. You should set `access-token` and allow unrestricted access (`"restricted": false`).
 
-### GET /1/config
+### JSON-RPC Interface
 
-Get current miner configuration. [Example](api/1/config.json).
+#### POST /json_rpc
 
+Control miner with JSON-RPC. Methods: `pause`, `resume`, `stop`, `start`
 
-### PUT /1/config
+Curl example:
+
+```
+curl -v --data "{\"method\":\"pause\",\"id\":1}" -H "Content-Type: application/json" -H "Authorization: Bearer SECRET" http://127.0.0.1:44444/json_rpc
+```
+
+### APIVersion 2
+
+#### GET /2/config
+
+Get current miner configuration. [Example](api/2/config.json).
+
+#### PUT /2/config
 
 Update current miner configuration. Common use case, get current configuration, make changes, and upload it to miner.
 
 Curl example:
 
 ```
-curl -v --data-binary @config.json -X PUT -H "Content-Type: application/json" -H "Authorization: Bearer SECRET" http://127.0.0.1:44444/1/config
