NASA Open APIs at api.nasa.gov are free of charge to all consumers. There are no paid tiers or commercial plans; access is governed by a single signed-up API key tier (1,000 requests per hour) and a shared DEMO_KEY for evaluation (30 per hour, 50 per day per IP). Higher limits require contacting [email protected].
