# 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 workflows.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 crate 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 workflows-agentdiet-dev-real-time-open-source-package-cve-ghsa-a4d90af3
```

Example prompt: Can you check if the PyPI package 'requests' has any known CVEs or GHSA security advisories right now, and tell me which version I should upgrade to if it's vulnerable?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates. It is backed directly by Google OSV.dev, making it more current than static NVD snapshots. Prefer it for CI/CD security gates, dependency audits, or agent-driven supply chain risk checks where freshness of CVE/GHSA data is critical.

## Known failure modes

- Package not found in any ecosystem — returns empty vulnerability list or 404-equivalent
- Malformed package identifier (wrong ecosystem prefix or missing name) — returns validation error
- OSV.dev upstream unavailable — may return a timeout or 503 error
- Ambiguous package name without ecosystem prefix may return results for wrong ecosystem
- Rate limiting or payment failure returns 402 with payment required

## 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://workflows.agentdiet.dev/v1/cve)

## Output

Returns a structured list of active vulnerability records for the queried package, including CVE and GHSA identifiers, severity ratings, affected version ranges, and the earliest patched version available, sourced live from Google OSV.dev.
