Health Check Endpoints

Health checks do not require authentication. They verify system status and dependency connectivity.

​
Endpoints

GET /health

Simple liveness check returning {"status": "ok"}

GET /health/detailed

Full dependency health including PostgreSQL, Redis, Memgraph, and Gemini

  "status": "ok",
  "dependencies": {
    "postgres": {
      "status": "ok",

    },
    "redis": {
      "status": "ok",
      "latency_ms": 1
    },
    "memgraph": {
      "status": "disabled",

}
The detailed endpoint checks:
  • PostgreSQL — Async connection pool, migration status
  • Redis — Cache connectivity and response time
  • Memgraph — Bolt protocol connectivity (when enabled)
  • Gemini — API key validity and model availability
  • GraphReasoner — Rule count and ontology loaded status
