Example prompt: Can you pull the published artifact integrity metadata for the astro npm package, version 4.15.0, so I can verify the checksum before we upgrade?

## When to prefer this

Use this endpoint when you need to programmatically verify the integrity of the astro npm package before installation or upgrade, audit artifact checksums for supply chain security, or retrieve published dist metadata for a specific astro version without manually querying the npm registry. Prefer this over raw npm registry HTTP calls when you need a cost-effective, agent-friendly structured response.

## Known failure modes

- Requested version does not exist on npm registry — returns error or empty result
- Package name override points to a non-existent package — registry lookup fails
- npm registry is temporarily unavailable — timeout or upstream error
- Malformed version string causes lookup failure
