How to properly query Kafka REST Proxy?

I'm running a dockerized distribution of Confluent platform:

Kafka REST Proxy is running on port 8082

When I issue an HTTP GET call against the REST proxy:

curl  --silent -X GET http://10.0.0.253:8082/kafka/clusters/ | jq 

All I get is:

{
  "error_code": 404,
  "message": "HTTP 404 Not Found"
}

Given my configuration, what can I change to actually get some useful information out of Kafka REST Proxy?

apache-kafka

confluent-platform

kafka-rest
