Every few months someone asks how to scrape WHOIS at scale, and the answers are always the same: port 43 sockets, regex soup for 200 registrar formats, and rate limits that ban you by lunchtime. Almost nobody mentions that the registries replaced the whole thing years ago with a JSON protocol called RDAP, and it is open, keyless, and standardized.
