Looks like a decent tool, but I personally would not use it in production. Took a few minutes to look through the code: They basically use the HTML pages instead of the APIs. What puts me off is that the code is missing tests altogether and has quite a few separation of concern issues. HTML extraction is everywhere, storage is embedded into the package. Cool proof of concept, not ready for production, I think.

Minor stuff: Printing instead of logging. Would prefer a package that only does the retrieval and nothing else. Hardcoded SQL(ite?) storage.
