# 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 live vulnerability data for a named open-source package and returns active CVEs, GHSA advisories, and patched version information.

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-2ba822c5
```

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

Choose this endpoint when you need real-time, live vulnerability data for a specific open-source package across PyPI, npm, Go modules, or Rust crates — particularly when you want CVE and GHSA advisory details with patched version information sourced directly from Google OSV.dev. Prefer it over static advisory databases when freshness matters, such as just before a deployment or when evaluating a new dependency.

## Known failure modes

- Unknown or misspelled package name returns empty results or an error
- Unsupported ecosystem prefix causes a lookup failure
- OSV.dev upstream unavailability causes timeout or degraded response
- Malformed 'Ecosystem:name' format may return no results
- 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/maven-vuln-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory references, affected version ranges, patched/safe versions, and severity metadata sourced live from Google OSV.dev for the requested package.
