# v2 health check (no auth)

`GET /health`

## Request

- Base URL: `https://docs.backquant.com/v2`
- URL: `https://docs.backquant.com/v2/health`
- Auth: API key in header `X-API-Key`

Lightweight liveness/readiness probe for external monitors. Reports overall status plus per-subsystem (redis, db) flags. Auth-free — uses the same `check_connection_health()` Fly.io's load balancer hits at `/health`. Rate limit: **60/minute per IP**.

Status values: `ok` (all subsystems healthy), `degraded` (one subsystem failing), `unhealthy` (cache + DB both unreachable).

## Response `200`
