while true; do
  outfile="${output_prefix}-${n}.json"
  url="${api_endpoint}?skip_status=true&count=200&cursor=${cursor}"

  echo "calling $url and sending output to $outfile"
  twurl $url > $outfile

  error_code=$(jq '.errors[0].code' < $outfile)
  if [ "$error_code" == "88" ]; then
    echo "Rate limited. Let's wait a minute."
    sleep 60
    rm $outfile
    continue
  else
    cursor=$(jq '.next_cursor' < $outfile)
  fi

  if [ $cursor == "0" ]; then
    echo "done"
    break
  fi

  sleep 2

done
