# Full API smoke test: list, update, and delete for gateways, zones,
# tracker zones, and trackers. Followed by a pagination showcase for
# every list endpoint.
#
# The script reads existing records from the database and exercises
# update + delete on them, so it is safe to run against a populated
# dev environment. Nothing is created — only existing rows are touched.
#
# Requires: jq   (https://stedolan.github.io/jq/)
#
# Usage:
#   ./api/smoke_test.sh
#   BASE_URL=http://host:port ./api/smoke_test.sh
