# 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 active CVEs, GHSA advisories, and patched versions for a given PyPI, npm, Go, or Rust crate 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-2dfd0a49
```

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 have been patched?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for packages across PyPI, npm, Go modules, or Rust crates, and want both CVE and GHSA advisories in a single call. Prefer it over static databases when freshness matters — e.g., before deployments or dependency audits — and when you need specific patched version guidance.

## Known failure modes

- Package not found in the specified ecosystem returns empty or error response
- Invalid ecosystem prefix causes a parsing or 400 error
- OSV.dev upstream unavailability may cause timeout or 503
- Malformed package identifier (missing colon or typo) returns no results
- Package with no known vulnerabilities returns an empty advisory 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/go-module-cve)

## Output

Returns a structured list of active CVEs and GHSA advisories for the queried package, including advisory IDs, severity, affected version ranges, and patched/fixed versions sourced live from Google OSV.dev.
