# 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 x402-audit.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 any PyPI, npm, Go, or Rust package.

## 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 x402-audit-agentdiet-dev-real-time-open-source-package-cve-ghsa-16473835
```

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

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when you need both CVE and GHSA advisory coverage in a single call with patched version guidance. Prefer it over static NVD lookups when freshness matters or when auditing supply chain risk before deployment.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Malformed package identifier format causes a 400 bad request error
- Upstream OSV.dev API unavailability leads to timeout or 503 error
- Payment not processed (HTTP 402) if x402 payment header is missing or insufficient
- Ambiguous package name without ecosystem prefix may return incorrect results

## 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://x402-audit.agentdiet.dev/v1/epss-scanner)

## Output

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