## API Notes

**HTTPS REQUIRED:** TrueNAS auto-revokes API keys used over HTTP.

> **REST API Deprecation Notice:** The REST API (`/api/v2.0/`) is deprecated in TrueNAS 25.04
> and **fully removed in 26.04**. Use the WebSocket API (via `scripts/truenas-ws.mjs`) as
> the forward-compatible method. REST examples below still work on 24.10 and 25.x.

### REST API (Legacy)

```bash
curl -sk "$TRUENAS_URL/api/v2.0/[endpoint]" \
  -H "Authorization: Bearer $TRUENAS_API_KEY"
```

The `-k` flag is needed for self-signed certificates (common on home servers).

### WebSocket API (Recommended)

The WebSocket API uses a DDP-like protocol (Meteor style). REST paths become dot notation:
`/api/v2.0/app` → `app.query`, `/api/v2.0/system/info` → `system.info`.

```javascript
// Connect: wss://<host>/websocket (rejectUnauthorized: false for self-signed)

// 1. Handshake
send: {"msg": "connect", "version": "1", "support": ["1"]}
recv: {"msg": "connected", "session": "..."}

// 2. Authenticate
send: {"id": "1", "msg": "method", "method": "auth.login_with_api_key", "params": ["API_KEY"]}
recv: {"id": "1", "msg": "result", "result": true}

// 3. Call methods
send: {"id": "2", "msg": "method", "method": "system.info", "params": []}
send: {"id": "3", "msg": "method", "method": "app.query", "params": []}
```

Use the helper script for WebSocket calls: `node scripts/truenas-ws.mjs <method> [params_json]`

## Security Notes

- **Self-signed certificates:** TLS verification is skipped by default (`curl -k`, `rejectUnauthorized: false`) because homelab servers typically use self-signed certs. Set `TRUENAS_VERIFY_TLS=1` to enforce strict TLS validation.
- **API key scope:** Use a read-only or least-privilege API key when possible. TrueNAS lets you scope keys to specific endpoints.
- **Credentials stay local:** All env vars are read at runtime and sent only to the configured service endpoints. Nothing is phoned home.

## Core Operations

### System Info

```bash
curl -sk "$TRUENAS_URL/api/v2.0/system/info" -H "Authorization: Bearer $TRUENAS_API_KEY"
```

### Pool Health

```bash
# All pools with health status
curl -sk "$TRUENAS_URL/api/v2.0/pool" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, healthy}'

# Or via WebSocket
node scripts/truenas-ws.mjs pool.query '[]'
```

The API returns a `.healthy` boolean per pool. For deeper status, inspect the full pool object.

### Active Alerts

```bash
curl -sk "$TRUENAS_URL/api/v2.0/alert/list" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {level, formatted}'
```

### Running Services

```bash
curl -sk "$TRUENAS_URL/api/v2.0/service" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.state == "RUNNING") | .service'
```

## Dataset Management

### List Datasets

```bash
curl -sk "$TRUENAS_URL/api/v2.0/pool/dataset" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, type, used: .used.parsed, available: .available.parsed}'
```

### Create Dataset

```bash
curl -sk -X POST "$TRUENAS_URL/api/v2.0/pool/dataset" \
  -H "Authorization: Bearer $TRUENAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "pool/path/new-dataset"}'
```

### Delete Dataset

```bash
# Destructive — confirm with user first
curl -sk -X DELETE "$TRUENAS_URL/api/v2.0/pool/dataset/id/DATASET_ID" \
  -H "Authorization: Bearer $TRUENAS_API_KEY"
```

## Snapshots & Replication

### List Snapshots

```bash
# WebSocket (required on 25.10+, /api/v2.0/zfs/snapshot returns 404)
node scripts/truenas-ws.mjs zfs.snapshot.query '[]'
```

### Create Snapshot

```bash
node scripts/truenas-ws.mjs zfs.snapshot.create '[{"dataset": "pool/dataset", "name": "manual-YYYY-MM-DD"}]'
```

### Snapshot Task Status

```bash
curl -sk "$TRUENAS_URL/api/v2.0/pool/snapshottask" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {dataset, schedule, enabled}'
```

### Replication Health

```bash
curl -sk "$TRUENAS_URL/api/v2.0/replication" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, state: .state.state}'
```

## App Management

TrueNAS Apps are the official marketplace for installing containerized services.

### List Installed Apps

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, state, version}'
```

### Check for Updates

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.upgrade_available) | .name'
```

### Install / Update Apps

See `references/app-installation.md` for the full installation guide covering:
- Checking app templates and storage requirements
- Creating datasets with proper ACLs
- Installing with correct storage mappings
- Handling apps with multiple storage mounts

### App Status

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app?name=APP_NAME" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[0] | {name, state, portals}'
```

## Dockge (Docker Compose Stacks)

Dockge is a companion UI for Docker Compose stacks not in the TrueNAS Apps catalog.
It uses Socket.IO, not REST. Use the provided scripts.

### Prerequisites

```bash
npm install   # in this skill's root directory
```

### List Stacks

```bash
node scripts/dockge-list.mjs
```

### Update Stacks

```bash
# Update all running stacks
node scripts/dockge-update.mjs

# Update specific stacks
node scripts/dockge-update.mjs mystack1 mystack2
```

### Socket.IO Protocol Details

Dockge uses Socket.IO with WebSocket transport.

**Status codes:**
- 1 = inactive/exited
- 3 = running
- 4 = updating

**Key events:**
- `login` — authenticate with username/password
- `stackList` — get all stacks (received via `agent` event)
- `agent`, "", "updateStack", stackName — trigger pull + restart

**Note:** Stacks prefixed with `ix-` are TrueNAS-managed apps visible to Dockge — skip those when updating.

## Monitoring Checklist

Run these commands for a quick health overview:

```bash
# Pool health
curl -sk "$TRUENAS_URL/api/v2.0/pool" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, healthy}'

# Active alerts
curl -sk "$TRUENAS_URL/api/v2.0/alert/list" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {level, formatted}'

# Running services
curl -sk "$TRUENAS_URL/api/v2.0/service" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.state == "RUNNING") | .service'

# App updates available
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.upgrade_available) | .name'

# Replication status
curl -sk "$TRUENAS_URL/api/v2.0/replication" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, state: .state.state}'
```

## Homelab Services

This skill includes reference files for common homelab service categories. Each covers
API patterns, env vars, and common agent tasks for services that typically run alongside
TrueNAS:

| Reference | Services | File |
|-----------|----------|------|
| Media management | Overseerr, Sonarr, Radarr, Prowlarr, Plex, Tautulli | `references/media-management.md` |
| App installation | TrueNAS native app install guide | `references/app-installation.md` |
| Download clients | qBittorrent, SABnzbd, FlareSolverr | `references/downloads.md` |
| Homelab services | ntfy, Syncthing, n8n, NocoDB, ChangeDetection, Crafty | `references/homelab-services.md` |
| Books & media | Audiobookshelf, LazyLibrarian, Calibre-Web, MeTube | `references/books-and-media.md` |
| Bookmarks | Karakeep (AI-powered bookmark manager) | `references/bookmarks.md` |

Load the relevant reference file when the user asks about a specific service category.

## Common Tasks

### "Check NAS health"

Run the monitoring checklist above. Summarize pool states, alerts, and any pending updates.

### "What's running?"

```bash
# TrueNAS apps
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.state == "RUNNING") | .name'

# Dockge stacks (if configured)
node scripts/dockge-list.mjs
```

### "Install an app"

Follow the guide in `references/app-installation.md`:
1. Check app template for storage requirements
2. Create dataset(s) under the apps pool
3. Set ACL with apps preset
4. Install app with correct storage mappings

### "Take a snapshot"

```bash
node scripts/truenas-ws.mjs zfs.snapshot.create '[{"dataset": "pool/dataset", "name": "manual-snapshot-name"}]'
```

### "What's downloading?"

See `references/downloads.md` for qBittorrent and SABnzbd API commands.

### "Add a movie/show"

See `references/media-management.md` for Overseerr request workflow.
