Automate monitoring RSS feeds and GitHub repositories by configuring a polling script to check external sources and report new items. This process uses a persistent watermark system to ensure you only receive alerts for newly detected updates.

Watermark deduplication prevents redundant alerts when polling JSON APIs by persisting state to the local filesystem. It tracks previously seen data items using a watermark, ensuring subsequent polls only surface newly detected content since the last check.

You need a standard Python 3 environment to run automated web polling scripts, along with local filesystem access for state persistence. The polling mechanism relies on this filesystem access to store the watermark data required for tracking new items.

You can track GitHub repository activity including issues, pulls, releases, and commits automatically without writing custom API code. The polling system queries GitHub repositories directly and uses watermark deduplication to alert you only when new project activity occurs.

The best way to get notifications for new items in a JSON API without duplicate alerts is using a persistent watermark system. It polls the API endpoint, saves the state of seen items to the local filesystem, and only reports data that appears after the last watermark.
