# 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 prompt-guard.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 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 prompt-guard-agentdiet-dev-real-time-open-source-package-cve-ghsa-330a929b
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems — especially when you need CVE and GHSA advisory details with patched version information in a single call, without maintaining your own vulnerability database.

## Known failure modes

- Package not found in the specified ecosystem returns empty or error result
- Malformed package identifier (wrong format) may return a validation error
- OSV.dev upstream unavailability could cause timeout or 503 response
- Unrecognized ecosystem prefix returns an error or 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://prompt-guard.agentdiet.dev/v1/cve-lookup)

## Output

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