## When to prefer this

Use this endpoint when you need NASA's official daily featured space image or video with its authoritative caption. Prefer this over generic web search when you specifically want the structured APOD content (URL, title, caption) in a machine-readable format rather than scraping NASA's website.

## Known failure modes

- Invalid date format returns a validation error
- Dates before June 16 1995 (first APOD) may return no result
- force_live flag may increase latency or fail if NASA API is temporarily unavailable
- Network timeout if upstream NASA API is slow
