# 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 Google OSV.dev in real time to return active CVEs, GHSA advisories, and patched version recommendations for PyPI, npm, Go, or Rust crate packages.

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-0a8fbf3e
```

Example prompt: Check OSV.dev for any active CVEs or GHSA advisories affecting the PyPI package 'requests' and tell me which versions are patched.

## When to prefer this

Prefer this endpoint when you need real-time, live vulnerability intelligence from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when you need CVE and GHSA advisories with patched version guidance in a single call. Use this over static NVD snapshots or bundled advisory databases when freshness is critical, such as during CI/CD pipelines, pre-deployment audits, or dependency review workflows.

## Known failure modes

- Unknown or misspelled package name returns empty or error response
- Ecosystem prefix missing or incorrect causes failed lookup
- OSV.dev upstream unavailability results in timeout or error
- Package with no known vulnerabilities returns empty advisory list
- Rate limiting or payment failure (HTTP 402) blocks the request

## 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/go-module-cve)

## Output

Returns a structured object containing a list of active vulnerabilities for the queried package, including CVE IDs, GHSA advisory identifiers, severity ratings, affected version ranges, and recommended patched versions sourced live from Google OSV.dev.
