## When to prefer this

Use this endpoint when you need to programmatically verify the integrity of the knex npm package before installation or upgrade — particularly in security audits, CI/CD pipelines, or supply chain reviews. Prefer it over manually querying the npm registry when you need a pay-per-call, agent-friendly wrapper with structured output.

## Known failure modes
