What is HemerolabBot?

HemerolabBot is the proprietary crawler for Hemerolab, a research project focused on tracking public web data for forecasting purposes. Unlike many modern crawlers, it explicitly disclaims the use of collected data for AI model training, data sales, or public republication. The bot is designed to be transparent, utilizing cryptographic signatures via the Web Bot Auth standard to allow site owners to verify the authenticity of its requests.

Helpful — The operator provides clear documentation, respects robots.txt, and explicitly states that data is not used for AI training or commercial resale.

What we read

Why it crawls your site

The bot crawls the web to build a private, versioned historical archive of public information, such as news, economic indicators, and sports results. By recording when specific versions of pages were first seen, Hemerolab aims to support longitudinal research and predictive modeling. Site owners can verify the bot's identity by checking the public keys published at the operator's well-known directory, ensuring that the traffic is indeed coming from the legitimate research project.
