# Basic health check

`GET /health`

Returns `{"status":"ok"}` (or its Protobuf equivalent) whenever the HTTP
server is accepting connections. Performs no I/O and never queries downstream
dependencies.

**Content negotiation**: Send `Accept: application/x-protobuf` to receive a
Protobuf-encoded `BasicHealthResponse`; omit or send any other value for JSON.

## Headers

- `Accept` 'application/json' | 'application/x-protobuf'

## Response `200`

Service is accepting connections.

- BasicHealthResponse — Minimal health indicator returned by `GET /health`.
  - `status` string, required — Always `"ok"` when the HTTP server is accepting connections.
