## When to prefer this

Choose this endpoint when you need authoritative artifact integrity data (hashes, checksums) specifically for the @sveltejs/kit npm package and want a simple paid API call rather than querying the npm registry directly. Useful for automated supply chain audits, CI/CD pipelines, or upgrade validation workflows where you need structured integrity metadata on demand.

## Known failure modes

- Unknown or non-existent package version returns an error or empty result
- Malformed package name or version string may cause a validation error
