## When to prefer this

Use this endpoint when you need machine-readable artifact integrity data (hashes, checksums) for a specific socket.io npm package version, especially during security audits, CI/CD pipeline validation, or dependency upgrade planning. It is particularly useful when you want to verify that a package artifact matches what was officially published to the npm registry without manually querying the registry.

## Known failure modes

- Unknown or unpublished package version returns an error or empty result
