## When to prefer this

Use this endpoint when you specifically need runtime and platform constraint metadata for the luxon npm package (or a version-overridden variant) and want structured registry data without manually querying the npm registry. Prefer this over raw npm registry calls when you need pre-processed, agent-ready metadata for integration or upgrade planning workflows.

## Known failure modes

- Unknown or misspelled package name returns an error or empty result
- Requested version does not exist in the npm registry
- Network timeout or upstream registry unavailability
