Lightweight Node.js server that pulls your Ollama cloud usage from ollama.com/settings and serves it as a JSON API. Runs fine on headless servers. Can optionally push metrics to Home Assistant.

No browser required on the server — just HTTP requests with cookie management.

Setup

cp .env.example .env   # Edit with your settings
npm install
npm start

Authentication

Pick one:

Option 1: Email/Password (if your account has a password)

Add to .env:

AUTH_MODE=email
OLLAMA_EMAIL=you@example.com
OLLAMA_PASSWORD=your-password

If you signed up with Google OAuth and never set a password, skip to Option 2.

Option 2: Export cookies from your browser (for Google/GitHub sign-ins)

Using a cookie extension like EditThisCookie or Cookie-Editor:

Install the extension, log into ollama.com
Export cookies for ollama.com as JSON
POST the JSON array to the server:

curl -X POST http://localhost:3214/api/cookies \
  -H "Content-Type: application/json" \
  -d @cookies.json

Or grab them manually from DevTools:

Log into ollama.com in your browser
Open DevTools → Application → Cookies → https://ollama.com
Copy each cookie's name/value and POST as JSON

Cookies get saved to .cookies.json and reused automatically. They'll expire eventually — when that happens, just re-export and POST them again.

Set in .env:

AUTH_MODE=cookies

API Endpoints

Endpoint	Method	What it does
`/api/usage`	GET	Latest usage data from last poll
`/api/usage/refresh`	GET	Force a fresh poll right now
`/api/health`	GET	Server status and config
`/api/cookies`	POST	Upload new cookies (JSON array)

Example response (`/api/usage`)

{
  "session": {
    "percent": 9.2,
    "resetsIn": "2 hours"
  },
  "weekly": {
    "percent": 32.9,
    "resetsIn": "3 days"
  },
  "fetchedAt": "2026-05-07T13:08:44.194Z"
}

Home Assistant Integration

Option A: Automatic push

Set HA_URL and HA_TOKEN in .env. After every poll, the server pushes to sensor.ollama_session_usage and sensor.ollama_weekly_usage. HA creates the sensors automatically — no manual setup needed.

Option B: REST sensor (pull from HA side)

Add to configuration.yaml:

sensor:
  - platform: rest
    name: Ollama Session Usage
    resource: http://localhost:3214/api/usage
    value_template: "{{ value_json.session.percent | default('unavailable') }}"
    unit_of_measurement: "%"
    state_class: measurement
    json_attributes:
      - session
      - weekly
      - fetchedAt
    scan_interval: 1800

  - platform: rest
    name: Ollama Weekly Usage
    resource: http://localhost:3214/api/usage
    value_template: "{{ value_json.weekly.percent | default('unavailable') }}"
    unit_of_measurement: "%"
    state_class: measurement
    scan_interval: 1800

Environment Variables

Variable	Default	Description
`AUTH_MODE`	`email` if password set, else `cookies`	`email` or `cookies`
`OLLAMA_EMAIL`	—	Email for email auth mode
`OLLAMA_PASSWORD`	—	Password for email auth mode
`PORT`	3214	Server port
`POLL_MINUTES`	30	How often to poll (minutes)
`HA_URL`	—	Home Assistant URL (no trailing slash)
`HA_TOKEN`	—	HA long-lived access token
`COOKIE_FILE`	`.cookies.json`	Where to store cookies

Updating Cookies

When cookies expire, just re-export from your browser and POST again — it replaces the old ones:

curl -X POST http://localhost:3214/api/cookies \
  -H "Content-Type: application/json" \
  -d @fresh-cookies.json

Server logs will show needsLogin when cookies have expired.
