The OpenRouter API Watcher is a tool that monitors changes in OpenRouter models and stores those changes in a SQLite database. It queries the model list via the API every hour and includes a simple web interface for viewing the changes.
For details how to run the OpenRouter API Watcher as user systemd service, see the INSTALL.
Quick overview: To run the OpenRouter API Watcher, you'll need a recent Node.js (v22). The tools/start.sh script includes the necessary installtion steps (assuming you are running on Mac or Linux):
- install a recent Node.js version via fnm
- install the necessary dependencies via npm
- generate the webclient and server code via tsc
- start the watcher
Note that tools/start.sh will not work if you have not setup a local production environment (see INSTALL).
The OpenRouter API Watcher includes a simple web interface that allows you to view the list of models and the changes that have been detected. By default, the web interface starts on a random, available port. Check the console output for the URL.
The OpenRouter API Watcher also includes a RSS feed generator, available at the /rss endpoint. It will serve the last 50 recorded changes as formatted JSON encapsulated in a <code> tag, so it does not look like a garbled mess in RSS readers.
You can run a set of simple test cases with the following command:
