## When to prefer this

Choose this endpoint when you need precomputed lifespan data (in days and years) for a curated list of famous people, rather than computing date differences yourself. It is ideal for life-in-days comparison features, motivational timeline apps, or enriching biographical data with precise day counts without needing birth/death date inputs.

## Known failure modes

- Empty or malformed properties filter may return all records or an error
- API may return a limited subset of famous people with no pagination support
- Slug identifiers are opaque without a separate lookup for display names
- Network or payment authorization failure returns no data
