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

## 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-c4ef6000
```

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

## 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 — particularly when freshness matters and you want direct OSV.dev intelligence rather than a cached or periodic scan. Prefer this over static SBOM tools when doing on-demand dependency checks before deployment or code review.

## Known failure modes

- Package not found in OSV.dev database — returns empty or no-vulnerability result
- Invalid ecosystem prefix causes lookup failure (e.g. wrong format like 'pypi' instead of 'PyPI')
- OSV.dev upstream API unavailability causes timeout or error
- Ambiguous package name without ecosystem prefix may resolve to wrong ecosystem
- Payment not processed (x402) results in 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://mesh.agentdiet.dev/v1/epss-scanner)

## Output

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