How this service works
Given an open-source package (PyPI, npm, Go, Cargo, Maven, NuGet or RubyGems) and optionally a version, returns its known vulnerabilities from OSV.dev (IDs, CVE aliases, severity, fixed-in versions), license, latest version, publish date and deprecation status from deps.dev, plus a one-line recommendation. For coding agents to call before adding or upgrading a dependency. Not charged if the package or version does not exist.
Output
A structured response containing: list of known vulnerabilities (OSV IDs, CVE aliases, severity ratings, fixed-in versions), the package license, latest published version, publish date, deprecation status, and a one-line human-readable recommendation on whether it is safe to use.
Example use cases
Pre-install vulnerability check for Python
“I'm about to pip install requests version 2.28.0 — can you check if it has any known CVEs or security issues before I add it to my requirements.txt?”
License audit before shipping
“We're about to ship a new feature that uses the npm package axios — can you look up its license and tell me if there are any vulnerabilities or deprecation warnings I should know about?”
Safe upgrade path for a Go module
“I need to upgrade golang.org/x/crypto in my Go project — can you check what the latest version is, whether the version I'm on has any known vulnerabilities, and what version fixes them?”
Technical details
Endpoint
GEThttps://x402.agentharbor.agency/package-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI coding agent needs a fast, pre-install safety check on a specific open-source dependency before adding or upgrading it in a project. It is ideal for catching known CVEs, verifying license compatibility, and confirming a package is not deprecated — all in a single call covering seven major ecosystems. Prefer this over raw OSV.dev or deps.dev API calls when you want a combined vulnerability + metadata + recommendation summary without stitching multiple APIs together.
Side effects
- Package or version does not exist — returns a not-found response (no charge)
- Ecosystem not supported — request rejected at schema validation
- Vulnerability data may lag OSV.dev update cadence
- Private or internal packages not discoverable via public registries
- Transitive (indirect) dependencies are not analyzed — only the specified package
