# 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 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-ea843071
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories, and tell me which versions have patches available?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates. It is particularly useful for automated security audits, CI/CD pipeline dependency checks, or when you need both CVE and GHSA advisory coverage in a single call with low cost per query ($0.01).

## Known failure modes

- Invalid or unrecognized package name returns empty vulnerability list or error
- Unsupported ecosystem prefix causes parsing failure
- OSV.dev upstream unavailability results in timeout or 5xx error
- Malformed 'Ecosystem:name' format may cause bad request
- Package with no known vulnerabilities returns empty advisories list

## 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/ghsa-advisories)

## Output

A structured response containing a list of known vulnerabilities for the specified package, including CVE identifiers, GHSA advisory IDs, vulnerability descriptions, affected version ranges, and recommended patched versions sourced from Google OSV.dev.
