# 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 live vulnerability data for a given PyPI, npm, Go, or Rust package and returns active CVEs, GHSA advisories, and recommended patched versions.

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-9f725b1c
```

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

## When to prefer this

Use this endpoint when you need live, real-time vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust packages specifically — especially when you need both CVEs and GHSA advisories in a single call. Prefer this over static NVD lookups when you need up-to-date patched version recommendations.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or error
- Invalid ecosystem prefix — query fails or returns unexpected results
- OSV.dev upstream unavailable — service returns timeout or 5xx error
- Malformed package identifier format — returns validation error
- No vulnerabilities found — returns empty advisories array (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://prompt-guard.agentdiet.dev/v1/maven-vuln-scanner)

## Output

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