Can anyone use the API key, e.g. does it require auth for both upload and download? For upload, is an archive.org userid sufficient, or is a separate API key needed? Will the new metadata be available via the API?

Onsite searches are usually less successful than a Google search with site:archive.org. Within the archive, it has been near impossible to create a URL-based search query that will find all editions of a given title/work. Will the new site/tagging help?

Thanks to the entire archive team for a precious resource.
