# 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-d9b60b38
```

Example prompt: Can you check if the PyPI package 'requests' has any active CVEs or GHSA advisories right now, and tell me which patched versions I should upgrade to?

## When to prefer this

Choose this endpoint when you need live, up-to-date CVE and GHSA vulnerability data for a specific open-source package across PyPI, npm, Go modules, or Rust crates — especially when you want authoritative Google OSV.dev intelligence without maintaining your own vulnerability database. Prefer this over static NVD snapshots or manual advisory lookups when freshness matters.

## Known failure modes

- Package not found in OSV.dev — returns empty or error response if the ecosystem/name is invalid
- Malformed package identifier (missing ecosystem prefix) may cause lookup failures
- OSV.dev upstream unavailability could cause timeouts or degraded responses
- Payment failure (HTTP 402) if the x402 micropayment is not properly resolved
- Rate limiting if the endpoint is called excessively in a short window

## 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)

## Output

Returns a structured JSON object containing active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, severity ratings, affected version ranges, and recommended patched versions for the queried package.
