Mediastack vs Spaceflight News
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.
Spaceflight News API is a free, keyless aggregator of space and astronomy news, articles, blogs, and reports pulled from NASA, ESA, and dozens of other spaceflight outlets, currently indexing more than 35,000 articles. The v4 API is fully open — no signup or API key needed — and returns paginated JSON with count/next/previous fields, plus a public OpenAPI/Swagger reference at its /v4/docs endpoint.
