# 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 for live CVE and GHSA vulnerability advisories for a given PyPI, npm, Go, or Rust crate package and returns affected versions and patches.

## 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-ee8fb9b9
```

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

## When to prefer this

Use this endpoint when you need live, real-time vulnerability intelligence from Google OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems. Prefer it over static advisory databases when freshness matters, or when you need a pay-per-call API without managing OSV.dev integration yourself.

## Known failure modes

- Package not found in OSV.dev — returns empty or error response
- Invalid ecosystem prefix causes query failure
- OSV.dev upstream unavailability results in timeout or error
- Malformed package identifier format returns 400-level error
- Package has 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/cve)

## Output

Returns a list of active CVE identifiers, GHSA advisory IDs, affected version ranges, severity information, and recommended patched versions for the queried package from Google OSV.dev.
