openlibrary-cli — Book Metadata from Open Library

Search books and authors, look up works and ISBNs, and fetch detailed metadata from the public Open Library API. No API key, no registration — just works.

Setup

No authentication or API keys needed. The Open Library API is fully public.

# Optional: set your email to help with rate limiting (included in User-Agent):
export OL_EMAIL="you@example.com"

Only Python 3.8+ and the requests package are required. --help and --dry-run work without any setup.
