 Generate a request with the `request` function:
 
 ```python
->>> from jsonrpcclient import request
+>>> from jsonrpcclient import request, request_json
 >>> request("ping")
-{"jsonrpc": "2.0", "method": "ping", "2.0", "id": 1}
+{'jsonrpc': '2.0', 'method': 'ping', 'id': 1}

+`request_json` gives you a string:
+
+```py
+>>> request_json("ping")
+'{"jsonrpc": "2.0", "method": "ping", "id": 2}'
+```
+
+It simply applies `str` after `request`.

 ## Ids
 
 Subsequent calls increment the `id`:

 ```
->>> request("ping")
-{"jsonrpc": "2.0", "method": "ping", "2.0", "id": 2}
->>> request("ping")
-{"jsonrpc": "2.0", "method": "ping", "2.0", "id": 3}

 ```
 
 Use an explicit `id`:
+
 ```
->>> request("ping", id="foo")
-{"jsonrpc": "2.0", "method": "ping", "2.0", "id": "foo"}
+
+> > > request("ping", id="foo")
