  title: NASA Open APIs (Artemis-relevant subset) APOD EPIC API
  version: 1.0.0
  summary: Best-effort OpenAPI for selected NASA Open APIs at api.nasa.gov used in Artemis-related workflows.
  description: 'api.nasa.gov is NASA''s umbrella developer portal exposing a number of

    long-standing public REST APIs. This spec covers the most widely used,

    stable endpoints relevant to Artemis-era lunar and space-weather workflows:

    APOD, the NASA Image and Video Library search, NeoWs (Near Earth Objects),

    DONKI space weather notifications, and EPIC Earth imagery.


    Authentication is a single api_key query parameter. The shared

    DEMO_KEY is rate-limited to 30 requests/hour and 50 requests/day per IP;

    sign up at https://api.nasa.gov/ for a higher-volume personal key.


    This is a best-effort spec derived from public api.nasa.gov documentation.
