# Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev)

> Real-Time Open-Source Package CVE & GHSA Vulnerability Scanner (OSV.dev) is a paid API for AI agents from polymarket-odds.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev in real time to return active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust package.

## 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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-ce0de489
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories and tell me which versions are patched?

## When to prefer this

Use this endpoint when you need real-time, authoritative vulnerability data for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is ideal for automated dependency audits, CI/CD security gates, or agent-driven supply chain checks where fresh CVE and GHSA data is critical. Prefer this over static SCA databases when currency of vulnerability intelligence matters.

## Known failure modes

- Unknown or misspelled package name returns no results or an error
- Ecosystem prefix mismatch (e.g. using 'pip' instead of 'PyPI') may cause lookup failure
- OSV.dev upstream unavailability results in a timeout or 5xx error
- Package with no known vulnerabilities returns an empty advisory list, which may be mistaken for an error
- Missing required 'package' parameter returns a 400 validation error

## How this service works

Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and returns active CVEs, GHSA advisories, and patched versions. (Live x402 v2, IETF MPP & MCP endpoint at https://polymarket-odds.agentdiet.dev/v1/osv-cve-vulnerability-radar)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory IDs, affected version ranges, severity details, and recommended patched versions for the queried package, sourced live from Google OSV.dev.
