A plain\n`GET /api/services` returns **21 real service names spanning both demo apps at\nonce**: HotROD's own (`frontend`, `route`, `driver`, `customer`) alongside the\nOpenTelemetry Demo \"astronomy shop\" services (`cart`, `checkout`, `currency`,\n`shipping`, `fraud-detection`, `recommendation`, `product-catalog`, `flagd`,\n`load-generator`, `image-provider`, `mysql`, and more) — confirming the\nOpenTelemetry Demo *is* publicly hosted here, not just distributable as a\ndocker-compose file as its own docs page implies (`opentelemetry.io/docs/demo/`\nlinks no live instance at all).\n\n```\nGET /api/services\n→ 200 {\"data\":[\"frontend\",\"jaeger\",\"load-generator\",\"product-reviews\",\"cart\",\n               \"flagd\",\"frontend-proxy\",\"ad\",\"recommendation\",\"product-catalog\",\n               \"quote\",\"redis-manual\",\"currency\",\"shipping\",\"checkout\",\"customer\",\n               \"driver\",\"fraud-detection\",\"image-provider\",\"mysql\",\"route\"],\n       \"total\":21,\"limit\":0,\"offset\":0,\"errors\":null}\n```\n\nA query for a nonexistent service (`service=doesnotexist123`) returns a clean\n**empty-but-200** result (`{\"data\":[],\"total\":0,...}`) rather than a 404 — classic\n\"absent\" rather than \"error\" shape.
