## When to prefer this

Use this endpoint when you specifically need artifact integrity metadata (checksums, tarball hashes) for the ajv npm package — particularly for security audits, supply chain verification, or upgrade planning workflows. Prefer it over generic npm registry lookups when you need structured integrity data ready for programmatic consumption without parsing raw npm API responses.

## Known failure modes
