# 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 versions for PyPI, npm, Go, or Rust 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-66cb4c23
```

Example prompt: Can you check if the npm package lodash has any active CVEs or GHSA security advisories, and tell me which versions have patches?

## When to prefer this

Use this endpoint when you need live, up-to-date vulnerability intelligence for PyPI, npm, Go, or Rust (crates.io) packages specifically, sourced directly from Google OSV.dev. Prefer it over static or cached vulnerability databases when currency of CVE/GHSA data matters, and when you need patched version details alongside advisory identifiers in a single call.

## Known failure modes

- Package not found in OSV.dev — returns empty advisory list or 404-style response
- Malformed package identifier (missing ecosystem prefix) — may return error or wrong results
- OSV.dev upstream API unavailability — returns timeout or service error
- Unknown ecosystem specified — returns validation error
- No vulnerabilities found — returns empty result set (not an error)

## 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/npm-vuln-scan)

## Output

Returns a structured list of active vulnerabilities for the queried package, including CVE IDs, GHSA advisory identifiers, affected version ranges, severity information, and the versions in which each vulnerability has been patched, sourced live from Google OSV.dev.
