I have a little pipeline that monitors specific parts of specific webpages for a value. If it changes, it makes a pull request to update a constant in a file. Basically, "if the minimum wage changes, update MINIMUM_WAGE in constants.json".
I use a tiny model (currently OpenAI, soon self-hosted Qwen) to extract values from raw text.
This helps me maintain a growing collection of guides about German bureaucracy. I monitor about a hundred values. I aim to watch as many facts as possible that way.
