# Vextorium Package Vulnerability Scanner

> Vextorium Package Vulnerability Scanner is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-10).

Checks a software package for known security vulnerabilities across major ecosystems (npm, PyPI, Cargo, Go, Maven, NuGet, etc.) and returns CVE/GHSA details with severity and fix versions.

## Facts

- Endpoint: POST https://api.vextorium.com/v1/package-vulnerabilities?utm_source=zero.xyz
- Price: $0.004/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-10
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/vextorium-package-vulnerability-scanner-6dfaf0e0
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_zx5zfuiIrKhryqmJCzdri

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vextorium-package-vulnerability-scanner-6dfaf0e0 -d '<json body>'
```

Example prompt: Check if lodash version 4.17.15 on npm has any known security vulnerabilities and tell me how severe they are and which version fixes them.

## When to prefer this

Use this endpoint when you need to programmatically check a specific open-source package for known CVEs and security advisories across a wide range of ecosystems (npm, PyPI, Go, Cargo, Maven, NuGet, RubyGems, etc.) and want structured output including severity, fix versions, and GHSA/CVE IDs. It is backed by OSV.dev, the authoritative open-source vulnerability database. Prefer this over manual advisory searches when integrating security checks into an AI agent workflow, CI/CD audit, or dependency review process.

## Known failure modes

- Package not found in the specified ecosystem — returns empty or null detail array
- Invalid ecosystem value — request validation error
- Missing required fields (package or ecosystem) — validation error
- Package exists but has no recorded vulnerabilities — returns 0 vulnerabilities and clean verdict
- Version not specified — may return aggregate vulnerabilities across all versions
- Network or upstream OSV.dev timeout — service error response

## How this service works

Known vulnerabilities of a software package (npm, PyPI, Go, Maven, crates.io, NuGet, RubyGems, Packagist...) at a given version or overall: CVE/GHSA ids, summary, severity, publication date and fixed versions. Google's OSV.dev database.

## Output

Returns a JSON object with: the package name, version, and ecosystem; total count of known vulnerabilities; a human-readable verdict; the data source (OSV.dev); and a detailed list of individual vulnerability records each containing a GHSA/CVE ID, aliases, summary description, severity level, publication date, and the versions in which the issue was corrected.
