# 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 live vulnerability data for a given open-source package and returns active CVEs, GHSA advisories, and patched versions.

## 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-100f4fda
```

Example prompt: Can you check if the PyPI package 'requests' has any active 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 CVE and GHSA vulnerability data for a specific open-source package across PyPI, npm, Go, or Rust ecosystems. It is backed directly by Google OSV.dev intelligence, making it preferable over static or cached vulnerability databases when up-to-date advisory data matters for security audits, CI/CD pipelines, or dependency vetting.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Invalid ecosystem prefix causes malformed query
- OSV.dev upstream unavailability leads to timeout or error
- Ambiguous package name without ecosystem prefix may return unexpected results
- Payment failure (HTTP 402) blocks access if x402 funds are insufficient

## 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/zero-day-advisories)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, vulnerability descriptions, severity information, and recommended patched versions for the queried open-source package, sourced live from Google OSV.dev.
