# 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 hn-pulse.agentdiet.dev, paid per call via MPP, $0.015/call, status unknown (last checked 2026-10-21).

Queries the Google OSV.dev database for a given open-source package and returns active CVEs, GHSA advisories, and patched versions in real time.

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 hn-pulse-agentdiet-dev-real-time-open-source-package-cve-ghsa-2dd14401
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories, and let me know what patched version I should upgrade to?

## When to prefer this

Prefer this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go, or Rust ecosystems, especially when you require advisory metadata (IDs, severity, patched versions) sourced directly from Google OSV.dev rather than a static or cached database.

## Known failure modes

- Package not found in OSV.dev database — returns empty advisory list or 404-style error
- Invalid package identifier format — returns validation error requesting 'Ecosystem:name' format
- OSV.dev upstream unavailable — may return timeout or 503
- No vulnerabilities found — returns empty results (not necessarily an error)
- Payment failure via x402 — returns 402 if micropayment is not completed

## 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://hn-pulse.agentdiet.dev/v1/ghsa-advisories)

## Output

Returns a structured object listing all active CVEs and GHSA advisories for the queried package, including advisory IDs, severity levels, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
