Chronicling America vs NewsData
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.
newsdata.io bundles breaking, crypto, and market-news search behind a credit-based JSON API: the free plan grants 200 credits/day at 10 articles per credit, with articles delayed 12 hours. Paid tiers unlock same-day delivery, multi-year historical archives, AI-generated tags and summaries, and sentiment scoring. Every plan authenticates with a single apikey query parameter.
