# 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 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-df4ed50e
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA security advisories, and tell me which versions have been patched?

## 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 want CVE and GHSA advisories with patched version recommendations in a single call. Prefer this over static vulnerability databases or offline SBOMs when freshness matters, such as pre-deployment checks or CI/CD security gates.

## Known failure modes

- Invalid or unrecognized package identifier returns empty or error response
- Ecosystem prefix not supported (only PyPI, npm, Go, crates.io) may yield no results
- Package with no known vulnerabilities returns an empty advisories list
- OSV.dev upstream unavailability causes request timeout or failure
- Malformed 'Ecosystem:name' format causes parameter validation error
- Payment failure (HTTP 402) blocks the request if x402 funds are insufficient

## 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/go-module-cve)

## Output

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