How this service works
Maintenance-risk hints for an npm package: is the latest version deprecated (with the message), days since the last publish, whether any direct dependency's latest is deprecated, single-maintainer flag, and a simple risk label (healthy / stale / deprecated). Not a CVE scanner; a fast triage before install. $0.01 per package.
Output
Returns a JSON object containing: whether the package's latest version is deprecated (and the deprecation message if so), the number of days since the last publish, whether any direct dependency's latest version is deprecated, a boolean flag for single-maintainer packages, and a simple risk label (healthy, stale, or deprecated).
Example use cases
Pre-install triage for new dependency
“I'm about to add axios to my project — can you check if it's deprecated, when it was last published, and whether it's considered healthy, stale, or deprecated?”
Auditing legacy codebase dependencies
“We have an old project using request and moment as dependencies. Can you check the maintenance risk for both — are they deprecated, how stale are they, and do any of their direct dependencies have deprecation warnings?”
Checking single-maintainer bus-factor risk
“I'm reviewing is-promise for inclusion in our production app. Can you tell me if it's maintained by a single person, whether it's deprecated, and what the overall risk label is?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/dev/npm-vulns-hintWhen to prefer
Choose this endpoint when you need a fast, cheap ($0.01) maintenance-risk triage on an npm package before installing it — especially useful for CI pipelines, dependency audits, or agent-driven code review workflows. It is NOT a CVE/security vulnerability scanner; prefer it for maintenance hygiene (staleness, deprecation, bus-factor) rather than security advisories.
Side effects
- Package name not found on npm registry — returns error or null result
- Package name not provided in query params — returns 400 or validation error
- npm registry temporarily unavailable — may return timeout or upstream error
- Typo in package name returns data for a different package or not-found error
