Hi everyone,

I'm working on a personal RAG-based search tool to quickly find problems, editorials, and relevant blog posts (for example: "problems on DP with bitmask that have a detailed explanation").

I know how to scrape the data manually, but honestly, I'd really prefer not to. Why?

I don't want to put unnecessary load on Codeforces servers. I'm afraid of getting banned even with polite delays. It feels wasteful to scrape the same data that someone might already have collected. So I'm wondering — does a dataset of Codeforces problems, editorial content, and educational blog posts already exist? Something like an archive or a collection that the community maintains?

If not — what would be the most respectful way to collect this kind of data without causing any trouble? (I'm okay with waiting, using APIs where possible, or joining some existing effort.)

Thanks in advance!
