Build a Basic Health Check Route

What you will practice

Requirements

• Register a `GET /health` route on the existing FastAPI `app` instance in `main.py`.
• The route must respond with HTTP status code 200.
• The response body must be JSON with exactly two keys: `status` and `uptime_seconds`.
• `status` must always be the string `"ok"`.
• `uptime_seconds` must be a Python `int` (not a `float`, not a `bool`).
• `uptime_seconds` must reflect whole seconds since the process started — it must grow monotonically across requests, never reset to 0 on a fresh request.

Starter files

What the judge checks

• Runs in the python environment with the python-pytest runner.
• Uses a 5000ms judge budget.
• Behavior rules include: Health Route Returns 200, Response Status Ok, Uptime Seconds Is Integer, Uptime Grows Monotonically.

Constraints

• Use FastAPI for route definition (the app object is already created in `main.py`).
• Response body must be valid JSON.
• `uptime_seconds` must be a Python `int`, not a `float`.

Example behavior

GET /health (immediately after the app starts)

200 OK
{"status": "ok", "uptime_seconds": 0}

GET /health (10 seconds after the app starts)

200 OK
{"status": "ok", "uptime_seconds": 10}

Follow-up

How would you extend `/health` to also report the status of each external dependency (database, Redis, etc.) without making the route slow under normal traffic?
