How this service works

Package vulnerability lookup API. Is this package version safe to install? Known vulnerabilities (CVE/GHSA ids, severity, CVSS score, fixed-in versions) and malicious-package flags for one npm, PyPI, Go, crates.io, Packagist, RubyGems, Maven or NuGet package version, from OSV.dev. Search intents: package vulnerability check, is this npm package safe, cve lookup api, pypi vulnerability, malicious package check, osv lookup.

Output

A JSON object containing a verdict ('vulnerable' or 'safe'), a list of packages with per-package vulnerability details including CVE IDs, CVSS scores, severity tiers, affected versions, fix versions, malicious flags, and summary counts (advisory count, vulnerable count, malicious count, highest severity).

Example use cases

Pre-install security check for CI/CD

“Before we deploy, can you check if express version 4.18.2 on npm has any known CVEs or malicious flags? I need severity and fix info.”

Python dependency audit before release

“We're about to ship a release using requests 2.27.1 from PyPI — can you scan it for security vulnerabilities and tell me the highest severity found?”

Supply chain safety check for Rust crate

“I'm adding serde 1.0.130 from crates.io to our project — does it have any known vulnerabilities I should worry about?”

When to prefer

Choose PkgGuard when you need a quick, pay-per-call vulnerability check against OSV.dev for a specific package version without setting up your own OSV API integration. It is especially useful in agentic pipelines that need to gate on security verdict before installing or deploying a dependency, and when you need structured JSON output with severity and fix-version data. Prefer alternatives if you need bulk scanning of entire lock files, continuous monitoring, or a source beyond OSV.dev.

Side effects

Package name or version not found in OSV.dev — returns empty vulnerability list
Unsupported ecosystem string — defaults to npm or returns error
Missing required 'name' or 'version' query parameters — returns 400 error
OSV.dev upstream unavailable — service may return 503 or timeout
Version string must be exact — fuzzy or range versions may not match advisories correctly
