Muusikoiden.Net market monitor

Regularly polls https://muusikoiden.net/tori/haku.php with user-defined search queries and returns new listings via a dedicated Telegram bot.

User interface in Telegram:

Installation

1. Create a Telegram bot

• In Telegram, open a chat with @BotFather
• Create a bot /newbot, give it a name, e.g. muus_watcher_bot
• Record the provided HTTP API token
• Navigate to the configuration menu: /mybots -> select the bot -> Edit Bot
  • Set the bot picture: select Edit Botpic and upload the provided bot_pic.png
  • Configure the user interface: select Edit Commands and paste the contents of bot_commands.txt

2. Configure the server

Python version:

• Install miniconda
• Create a conda environment: conda env create -f environment.yml
• In main.py:
  • Specify your bot token in TG_BOT_TOKEN = ""
  • (optional) Configure the update interval, i.e. how often to fetch the listings - QUERY_EXEC_INTERVAL (1 hour by default)

Rust version:

• In src/main.rs:
  • Specify your bot token in const TG_BOT_TOKEN: &str = "";
  • (optional) Configure the update interval, i.e. how often to fetch the listings - QUERY_COOLDOWN_INTERVAL (1 hour by default)

Usage

1. Start the server

Python version:

conda activate muus_watcher
python main.py

The server saves its state to db.yaml and restores it on restart.

Rust version:

cargo run 

The server saves its state to db.json and restores it on restart.

2. Configure listing search of your interest

• In Telegram, open a chat with @{your_bot_name}
• Register new user /start
• Add search query, e.g. /add arturia keylab -88 (includes listings with "Arturia", "Keylab", and without "88"). The query will be triggered once added and then repeatedly run with update interval specified above
• Inspect /list and remove queries (/remove _, /clear) as need.

Limitations

• [python-only] The server currently considers only the first page of query search results returned by https://muusikoiden.net/ . This means that if there are more 1 page of new listings added during the update interval, the earliest ones will not be reported in Telegram.
• The server reports the listings that were added or modified since the previous query search. Practically, this often results in repeated notifications if the seller edits their listing.
