Currents vs Spaceflight News

Currents API returns real-time and historical global news as JSON, with search filterable by language, keyword, country, category, and date range. A free account includes 1,000 requests/day — enough for prototyping — before paid plans raise the ceiling for production traffic. Authentication is a single API key passed on every request.

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.
