# 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 live OSV.dev vulnerability intelligence for a given open-source package and returns active CVEs, GHSA advisories, and patched version information.

## 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-7a69c88a
```

Example prompt: Can you check if the PyPI package 'requests' has any known 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 from OSV.dev for PyPI, npm, Go, or Rust (crates.io) packages, especially when you want both CVE and GHSA advisory coverage in a single call. It is preferable over static databases or NVD-only sources when freshness and cross-ecosystem breadth matter, and when you want patched version guidance alongside the advisory details.

## Known failure modes

- Package not found in OSV.dev — returns empty or error if the ecosystem/name combination is invalid
- Invalid package format — error if the 'Ecosystem:name' format is malformed
- No vulnerabilities found — returns an empty advisory list for packages with a clean record
- OSV.dev upstream unavailability — may return a timeout or 5xx if the backend is down
- Rate limiting or payment failure — 402 payment required if the x402 micropayment is not completed

## 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/ghsa-advisories)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, affected version ranges, severity levels, and the patched/fixed versions for the queried open-source package, sourced live from Google OSV.dev.
