 This NIP defines the verb `COUNT`, which accepts a subscription id and filters as specified in [NIP 01](01.md) for the verb `REQ`. Multiple filters are OR'd together and aggregated into a single count result.
 
-```
+```json
 ["COUNT", <subscription_id>, <filters JSON>...]
 ```
 
 Counts are returned using a `COUNT` response in the form `{"count": <integer>}`. Relays may use probabilistic counts to reduce compute requirements.
+In case a relay uses probabilistic counts, it MAY indicate it in the response with `approximate` key i.e. `{"count": <integer>, "approximate": <true|false>}`.
 
-```
+```json
 ["COUNT", <subscription_id>, {"count": <integer>}]
 ```
 
-Examples:
+Whenever the relay decides to refuse to fulfill the `COUNT` request, it MUST return a `CLOSED` message.
