AUTH NONECORS AGENT HTTPS COMMERCIAL ?

The Internet Archive's metadata endpoint returns everything it knows about an item: its files, formats, checksums, servers and descriptive fields, all as JSON. Just append an item identifier to /metadata/ — no key, no signup. Handy for building on top of the Archive's books, audio, video and web collections.
