Chronicling America vs GNews

Chronicling America is the Library of Congress's searchable archive of historic U.S. newspaper pages published through 1963, built from the National Digital Newspaper Program. As of August 2025 its data moved fully onto the general loc.gov JSON/YAML API, retiring the old chroniclingamerica.loc.gov endpoints in favor of structured search, batch, and full-text access — no API key is required, though heavy use should self-throttle.

GNews mirrors Google News rankings across roughly 80,000 sources, exposing search and top-headlines endpoints filterable by category, language, and country. The free plan is capped at 100 requests/day with articles delayed 12 hours and results limited to the last 30 days; paid tiers add same-day articles, a multi-year archive back to 2020, and higher daily caps. Every response is JSON, authenticated with a single API-key query parameter.
