# 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 mesh.agentdiet.dev, paid per call via MPP, $0.01/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 crate 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 mesh-agentdiet-dev-real-time-open-source-package-cve-ghsa-21d6b058
```

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 CVE and GHSA vulnerability data from Google OSV.dev for PyPI, npm, Go modules, or Rust crates, especially in automated security audits, CI/CD pipelines, or dependency review workflows where up-to-date advisory data is critical. Prefer it over static databases or periodic-update tools when freshness matters.

## Known failure modes

- Package not found in any ecosystem — returns empty or error if the package name is misspelled or unsupported ecosystem is specified
- Network or OSV.dev upstream unavailability — may return a timeout or 5xx error
- Ambiguous package name without ecosystem prefix — may match wrong ecosystem or fail to resolve
- Payment failure via x402 — 402 response if micropayment is not processed correctly

## 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://mesh.agentdiet.dev/v1/epss-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory details, affected version ranges, and patched/fixed versions for the queried open-source package, sourced live from Google OSV.dev.
