## When to prefer this

Use this endpoint when you need programmatic access to npm install lifecycle hook metadata for the 'ws' package or any other npm package, particularly for integration planning, upgrade safety checks, or security auditing of install-time scripts. Prefer this over manual npm registry lookups when automating dependency review workflows.

## Known failure modes

- Package name not found in npm registry — returns 404 or empty result
- Invalid version string causes lookup failure
- Rate limiting or payment failure returns 402 or 429
