-# MBID Poller
+# mbid-poller
 
-This project provides a polling mechanism, packaged in a **Docker container**, to routinely check the MusicBrainz ID (MBID) status for items and then optionally trigger a search in a **Lidarr** instance.
+A polling script to automatically add artists to Lidarr based on MusicBrainz IDs (MBIDs). The script fetches artist data from the Lidarr.audio API and adds them to your Lidarr instance with proper monitoring and quality profiles.
 
----
+With thanks to @kchiem for their perl script as the key piece of this image.
 
-## 💡 Acknowledgements
+https://gist.github.com/kchiem/eb998ac3c6f5a96cbec03b8e8c3b21a6
 
-The core logic for the polling mechanism in this project is based on an existing script generously shared by GitHub user **kchiem**.
+## Features
 
-We are utilizing and adapting the Perl script found in the following public Gist:
+- **Multiple Input Sources**: Support for API endpoints, JSON files, or single artist IDs
+- **Robust Error Handling**: Automatic retries for API timeouts and comprehensive error logging
+- **Validation**: Skips artists without albums to avoid cluttering your library
+- **Configurable Logging**: Switch between info and debug logging levels
+- **Docker Support**: Run as a containerized service
 
-* **Original Script:** `kchiem/lidarr-ping.dist`
+## Prerequisites
-* **Link:** https://gist.github.com/kchiem/eb998ac3c6f5a96cbec03b8e8c3b21a6
 
-We appreciate kchiem's contribution to the community!
+- Docker and Docker Compose
+- A running Lidarr instance
+- Lidarr API key (found in Lidarr Settings > General > API Key)
+- Quality and Metadata profile IDs from your Lidarr instance
 
----
+## Configuration
 
-## 🚀 Setup and Usage
+### Environment Variables
 
-This project is designed to run as a service alongside a **Lidarr** instance using Docker Compose.
+| Variable | Description | Required | Default |
+|----------|-------------|----------|---------|
+| `LIDARR_BASE` | URL to your Lidarr instance | Yes | `http://localhost:8686` |
+| `LIDARR_API_KEY` | Your Lidarr API key | Yes | - |
+| `LIDARR_ROOT_FOLDER` | Music root folder path in Lidarr | Yes | `/music` |
+| `LIDARR_QUALITY_PROFILE_ID` | Quality profile ID from Lidarr | No | `1` |
+| `LIDARR_METADATA_PROFILE_ID` | Metadata profile ID from Lidarr | No | `1` |
+| `LOG_LEVEL` | Logging verbosity (`info` or `debug`) | No | `info` |
 
-### 1. Prerequisites
+### Input Sources (choose one)
 
-Before starting, ensure you have:
+The script supports three input methods in order of priority:
 
-1.  **Docker** and **Docker Compose** installed.
+#### 1. API URL (Highest Priority)
-2.  A running **Lidarr** instance.
+```yaml
-3.  The project files (`Dockerfile`, `poller.pl`, `docker-compose.yaml`, etc.) in a single directory.
+- MBID_API_URL=http://your-api-server:port/artists
+```
+Fetches artist data from an API endpoint that returns JSON array with `foreignId` fields.
 
-### 2. Configure Docker Compose
+#### 2. JSON File (Second Priority)
+```yaml
+- MBID_JSON_FILE=/config/ids.json
+```
+Reads from a local JSON file with the same format as the API.
 
-The `mbid-poller` container needs to communicate with your Lidarr instance.
+#### 3. Single ID/URL (Lowest Priority)
+```yaml
+- MBID_URL=06f71b9e-639c-4903-bf6b-76b8893d3957
+```
+Processes a single MusicBrainz artist ID.
 
-1.  **Rename the Example:** Rename the provided `docker-compose.yaml.example` to `docker-compose.yaml`.
+### JSON Format
-2.  **Network Setup:** Ensure the `lidarr` and `mbid-poller` services are on the **same Docker network** (e.g., `example_network`). If you use a different setup (like host network), update `LIDARR_BASE` accordingly.
-3.  **Lidarr Base URL:** Verify the `LIDARR_BASE` environment variable in the `mbid-poller` service points to your Lidarr instance.
 
-    ```yaml
+For API or file input, use this JSON structure:
-    # Example for the default setup:
+```json
-    - LIDARR_BASE=http://lidarr:8686 
+[
-    ```
+  {
+    "foreignId": "06f71b9e-639c-4903-bf6b-76b8893d3957"
+  },
+  {
+    "foreignId": "c85cfd6b-b1e9-4a50-bd55-eb725f04f7d5"
+  }
+]
+```
 
-### 3. Choose the MBID Input Source
+## Usage
 
-The `poller.pl` script supports three different ways to provide MBIDs, in order of priority:
+### Docker Compose
 
-| Environment Variable | Priority | Description |
+1. Create your `docker-compose.yaml`:
-| :--- | :--- | :--- |
-| `MBID_API_URL` | **1st** (Highest) | A URL that returns a JSON array of objects, each containing a `foreignId` field. |
-| `MBID_JSON_FILE` | **2nd** | A path to a local JSON file (like `ids.json`) containing the MBID array. |
-| `MBID_URL` | **3rd** (Lowest) | A single MusicBrainz URL or ID to process. |
 
-In your `docker-compose.yaml`, **only one** of these should be uncommented and set.
+```yaml
-
+services:
-#### A. Using a JSON File (Recommended for simple setups)
+  mbid-poller:
-
+    build: .
-1.  Place your list of IDs in an `ids.json` file in the project directory (or adjust the volume mount).
+    container_name: mbid-poller
-2.  In `docker-compose.yaml`, **comment out** `MBID_API_URL` and **uncomment** `MBID_JSON_FILE`:
-
-    ```yaml
-    # ... mbid-poller environment section
     environment:
-      # ...
+      # Lidarr Configuration
-      - LIDARR_BASE=http://lidarr:8686
+      - LIDARR_BASE=https://your-lidarr-instance.com
-      # - MBID_API_URL= 
+      - LIDARR_API_KEY=your_api_key_here
-      - MBID_JSON_FILE=/config/ids.json
+      - LIDARR_ROOT_FOLDER=/data/music
-      # - MBID_URL=... 
+      - LIDARR_QUALITY_PROFILE_ID=1
+      - LIDARR_METADATA_PROFILE_ID=1
+      
+      # Logging
+      - LOG_LEVEL=info  # Use 'debug' for troubleshooting
+      
+      # Input Source (choose one)
+      - MBID_API_URL=http://your-api-server:port/artists
+      # - MBID_JSON_FILE=/config/ids.json
+      # - MBID_URL=06f71b9e-639c-4903-bf6b-76b8893d3957
     volumes:
-      - ./ids.json:/config/ids.json:ro # Maps your local file into the container
+      - ./ids.json:/config/ids.json:ro  # Only needed if using JSON file
-    ```
+    restart: "no"  # Run once
+    command: ["/app/poller.pl"]
+```
 
-### 4. Build and Run
+2. Build and run:
+```bash
+docker-compose up --build
+```
 
-With your files and `docker-compose.yaml` configured, you can build and run the poller.
+### Finding Profile IDs
 
-1.  **Build the Container:** This compiles the Perl dependencies using the `Dockerfile`.
+To find your Quality and Metadata Profile IDs:
 
-    ```bash
+1. Go to Lidarr Settings > Profiles > Quality Profiles
-    docker compose build mbid-poller
+2. Note the ID number in the URL when editing a profile
-    ```
+3. Go to Lidarr Settings > Profiles > Metadata Profiles
+4. Note the ID number in the URL when editing a profile
 
-2.  **Run the Poller:** Since the `restart` policy is set to `"no"`, this command will run the script once and exit.
+## Logging
 
-    ```bash
+### Info Level (Default)
-    docker compose up mbid-poller
+Clean output showing processing progress and results:
-    ```
+```
+--- Processing (1/165): 00d0f0fa-a48c-416d-b4ff-25a290ce82d8 ---
+- artist: Imagine Dragons
+- artist already exists in Lidarr or validation failed
+```
 
-The script will fetch the IDs, then loop through them, pinging the external MusicBrainz API until a successful response is received. It then outputs a Lidarr search URL for you to manually or automatically trigger the import in Lidarr.
+### Debug Level
+Verbose logging for troubleshooting:
+```
+[DEBUG] attempt 1: making request...
+[DEBUG] Lidarr API Response Code: 201
+[INFO] SUCCESS: Artist added to Lidarr
+```
+
+Set `LOG_LEVEL=debug` to enable debug logging.
+
+## How It Works
+
+1. **Fetch Artist List**: Retrieves MBIDs from your configured source
+2. **Query Lidarr.audio API**: Gets detailed artist information for each MBID
+3. **Validate**: Checks if artist has albums (skips if none)
+4. **Add to Lidarr**: Creates artist entry with monitoring enabled
+5. **Handle Duplicates**: Skips artists that already exist
+
+## Error Handling
+
+- **API Timeouts**: Automatic retry with exponential backoff (max 15 attempts)
+- **Missing Data**: Validates required fields before processing
+- **Duplicate Artists**: Gracefully handles artists already in Lidarr
+- **Network Issues**: Comprehensive error logging with specific HTTP status codes
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Artists not being added**: Set `LOG_LEVEL=debug` to see detailed API responses
+2. **Authentication errors**: Verify your `LIDARR_API_KEY` is correct
+3. **Profile errors**: Ensure `LIDARR_QUALITY_PROFILE_ID` and `LIDARR_METADATA_PROFILE_ID` exist
+4. **Path issues**: Check that `LIDARR_ROOT_FOLDER` exists and is writable
+
+### Debug Mode
+
+Enable debug logging to see:
+- Full API request/response details
+- Artist data field mapping
+- Lidarr API payloads
+- Step-by-step processing information
+
+## Output
+
+The script provides a summary at completion:
+```
+=== Processing Complete ===
+Summary:
+  Total processed: 165
+  Successfully added: 142
+  Errors: 3
+  Skipped (validation failed): 20
+```
