Do GNews and Open Library need an API key?
Open Library needs no key, while GNews requires a free API key. If you want to start calling without signup, reach for Open Library first.
Can I call GNews and Open Library from the browser?
Yes — both GNews and Open Library send CORS headers over HTTPS, so front-end code can fetch either directly with no backend proxy. That makes them easy to swap in a client-side app while you compare responses.
Are GNews and Open Library free for commercial use?
GNews has unclear commercial terms, and Open Library has unclear commercial terms. We track service terms and the data license as separate fields — see the Commercial use and Data license rows above, and confirm both before shipping either in a paid product.
