# 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 for active CVE and GHSA vulnerability advisories against a named PyPI, npm, Go, or Rust crate package, returning patched versions and risk details.

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 x402-audit-agentdiet-dev-real-time-open-source-package-cve-ghsa-7f4f07e3
```

Example prompt: Can you check if the npm package lodash has any known CVEs or GHSA security advisories right now, and tell me which version fixes them?

## When to prefer this

Choose this endpoint when you need real-time, live vulnerability data from OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates — especially when you want CVE and GHSA advisory details with patched version information in a single call, without maintaining your own vulnerability database or integrating directly with OSV.dev's API.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-vulnerability result
- Invalid ecosystem prefix causes parsing error or no results
- OSV.dev upstream unavailability leads to timeout or 503 error
- Malformed package identifier format returns validation error
- Payment not processed via x402 results in HTTP 402 response blocking the query

## 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/npm-vuln-scan)

## Output

Returns a structured list of active vulnerability records for the queried package, including CVE and GHSA identifiers, severity ratings, affected version ranges, and patched/fixed versions sourced live from Google OSV.dev.
