# 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 for live CVE and GHSA vulnerability data for a given open-source package across PyPI, npm, Go, or Rust ecosystems, returning active advisories and 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-e633e24a
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for PyPI, npm, Go, or Rust packages — especially when you want CVE IDs, GHSA advisory numbers, and patched version recommendations in a single call. Prefer it over static NVD lookups or local databases when freshness matters, or when building automated dependency auditing pipelines that need pay-per-call economics.

## Known failure modes

- Package not found in OSV.dev database — returns empty advisory list or 404-style error
- Invalid ecosystem prefix causes parsing failure — returns validation error
- OSV.dev upstream unavailable — service may timeout or return 503
- Ambiguous package name without ecosystem prefix may return unexpected results
- Rate limiting or payment failure (HTTP 402) if micropayment not satisfied

## 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/vuln-scanner)

## Output

Returns a structured response listing all active CVEs and GHSA advisories for the requested package, including advisory IDs, severity levels, affected version ranges, and the earliest patched version available, sourced live from Google OSV.dev.
