Do you need a simple way to validate that an API endpoint is responsive, but you don't want to use curl? There is a simple way to validate the endpoint with nc, producing an output that can be redirected to a logfile and parsed later: URL=$1 PORT=$2 while true; do RESULT=$(nc -vz $URL $PORT 2>&1) DATE=$(date) echo $DATE $RESULT sleep 1 done You can all this script with the API URL as first parameter, and API port as the second. netcat will be accessing to that endpoint and will report the results, detecting when the API is down. We also can output the date to have a reference when failures are detected.
