Mediastack vs NewsData

mediastack (now operated under APILayer) aggregates live and historical news and blog articles from thousands of worldwide sources into a single JSON REST endpoint keyed by an access_key parameter. Its free plan is capped at 100 calls/month with delayed news data and HTTP-only access — HTTPS, real-time delivery, and historical search all require moving to a paid Standard plan or higher.

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.
