Noozra vs Spaceflight News

Noozra aggregates headlines from more than 200 curated RSS sources into one JSON feed. No signup or API key is required, and every response carries an open CORS header. Requests are capped at 100 per day per IP, with separate endpoints for search, category listing, and the raw article feed.

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.
