+# UCP API test suite
+# Tests the Universal Commerce Protocol REST endpoints (cart, order) via curl.
+#
+# Prerequisites:
+#   make up-infra     (infra compose up — order :8092, cart :8090)
+#   OR full stack     (docker compose --profile "*" up — nginx on :8080)
+#
+# Usage:
+#   # Direct to Docker services (infra stack):
+#   bash api-tests/test_ucp.sh --infra
+#
+#   # Via nginx (full compose stack):
+#   bash api-tests/test_ucp.sh --edge
+#
+#   # Single service:
+#   bash api-tests/test_ucp.sh --order
+#   bash api-tests/test_ucp.sh --cart
+#
+#   # Verify signatures (requires signing key mounted):
+#   bash api-tests/test_ucp.sh --verify-sig
