Evidence-backed facts

  1. NASA Open APIs publish multiple scientific and media data services behind service-specific endpoints and parameters. informative
  2. DEMO_KEY supports limited exploration, while sustained applications should obtain their own key and obey response rate-limit headers. informative
  3. Default documented limits apply across api.nasa.gov requests for a key and can temporarily block callers that exceed them. informative
  4. A NASA API listing or DEMO_KEY response does not guarantee every service, asset, date, coordinate, or upstream data provider is available or complete. informative
