# Active Calls

`GET /api/v1/health/active-calls`

## Request

- Base URL: `https://app.dograh.com`
- URL: `https://app.dograh.com/api/v1/health/active-calls`
- Auth: none declared

In-flight call count for THIS worker — the drain signal for deploys.

A deploy orchestrator polls this per worker and waits for zero before
sending SIGTERM, because uvicorn force-closes live call WebSockets (close
code 1012) on SIGTERM and would cut calls mid-conversation otherwise. The
count is per-process: one uvicorn per VM port (scripts/rolling_update.sh)
or per Kubernetes pod (preStop hook). See api/services/observability/active_calls.py.
