## When to prefer this

Choose this endpoint when you need artifact-level integrity data (checksums, dist hashes) for a specific bullmq version from the npm registry — particularly useful for security audits, CI/CD pipeline validation, or upgrade planning where you need to verify the published artifact hasn't been tampered with. Prefer over generic npm API calls when you want a structured, agent-friendly response with integrity fields surfaced clearly.
