Example prompt: What are the runtime and platform constraints for dayjs version 1.11.10? I want to know which Node.js versions and operating systems it officially supports before I upgrade my project.

## When to prefer this

Use this endpoint when you need structured, machine-readable platform and runtime constraint data for dayjs specifically — particularly during dependency audits, upgrade planning, or CI matrix configuration. Prefer this over manually parsing npm registry JSON when you want pre-processed constraint metadata with integration context.

## Known failure modes

- Invalid or non-existent package version returns an error or empty constraints
- Network timeout if the npm registry is slow or unavailable
- Malformed version string causes validation failure
- Package name override to an unknown package returns no metadata
