How this service works
Package Vulnerability Check (OSV). Package vulnerability check before you install or ship a dependency: known vulnerabilities for a specific version from OSV.dev (GitHub advisories, PyPA, RustSec, Go, npm...) with CVE aliases, severity, fixed-in versions and the recommended upgrade. npm, PyPI, crates, Go, Maven, NuGet, RubyGems, Packagist, Pub, Hex.
Output
Returns a JSON object containing the package name, version queried, a boolean 'vulnerable' flag, an array of vulnerability objects from OSV, the highest severity level found (e.g. CRITICAL, HIGH, MEDIUM, LOW, or null), and a recommended upgrade version string (or null if none is available).
Example use cases
Pre-deploy dependency security audit
“Before I deploy my app, check whether express version 4.17.1 in the npm ecosystem has any known security vulnerabilities and what the recommended safe version would be.”
Python package vulnerability check
“Is requests version 2.25.0 in the pypi ecosystem vulnerable to anything? If so, what's the highest severity and which version should I upgrade to?”
Automated CI pipeline security gate
“Check if log4j version 2.14.1 in the maven ecosystem has any known vulnerabilities — I need to know if it's safe to use in production or if there's a patched version I should switch to.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/vuln/check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, per-package vulnerability check against the OSV database without running a full local scanner. It is ideal for CI/CD pipelines, agent-driven dependency audits, or single-package spot-checks across a wide range of ecosystems including npm, pypi, crates, go, maven, nuget, rubygems, packagist, pub, and hex. It is cheaper and simpler than integrating a full SCA (Software Composition Analysis) tool when only one package needs checking at a time.
Side effects
- Missing required query parameters (name, version, ecosystem) returns an error
- Unknown or unsupported ecosystem value returns an error or empty result
- Package not found in OSV database returns vulnerable=false with empty vulnerabilities array
- Network or upstream OSV API timeout may cause delayed or failed responses
- Malformed version string may result in no matches being found
