agent-api-production.tim1712.workers.dev/v1/npm/install-preflight

Use before a coding agent installs an unfamiliar npm dependency. Returns current facts from the official npm registry: the version `npm install` resolves (dist-tags.latest), prerelease and deprecation status, engines.node compatibility with an optional target Node version (real SemVer evaluation), license, days since release, best-effort weekly downloads, repository URL and maintainer count. Facts only — no safety, trust, or malware verdict.
