# 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.

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 polymarket-odds-agentdiet-dev-real-time-open-source-package-cve-ghsa-f0601a03
```

Example prompt: Check OSV.dev for any active CVEs or GHSA security advisories affecting the npm package lodash — I want to know what vulnerabilities exist and which versions have patches.

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems — especially when you want live CVE and GHSA advisories sourced directly from Google OSV.dev rather than a cached or third-party database. Prefer it for automated dependency audits, CI/CD security gates, or agent-driven supply chain risk checks where freshness of vulnerability intelligence matters.

## Known failure modes

- Package not found or unrecognized ecosystem returns empty or error response
- Malformed package identifier (missing ecosystem prefix) may cause ambiguous lookup or error
- OSV.dev upstream downtime results in failed or stale response
- Rate limiting or payment failure (HTTP 402) blocks the request
- Package with no known vulnerabilities returns an empty advisories list, which may be misread as an 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/cve-lookup)

## Output

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