## When to prefer this

Use this endpoint when you need to programmatically retrieve and verify artifact integrity metadata (checksums, hashes) for the dayjs npm package specifically — particularly for supply chain security audits, CI/CD pipeline validation, or pre-upgrade dependency verification. Prefer this over general npm registry queries when you want a structured, agent-friendly API response with integrity-focused metadata.

## Known failure modes
