# 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 serp-extract.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Queries Google OSV.dev 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 serp-extract-agentdiet-dev-real-time-open-source-package-cve-ghsa-670cb78c
```

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 been patched?

## When to prefer this

Use this endpoint when you need real-time, live vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go, or Rust ecosystems — particularly when you need CVE and GHSA advisories with patched version guidance. Prefer this over static NVD lookups or cached vulnerability databases when freshness matters for supply chain security decisions.

## Known failure modes

- Package not found in OSV.dev — returns empty or no-advisory response
- Invalid ecosystem prefix causes query failure (e.g. typo in 'PyPI:')
- OSV.dev upstream API unavailability leads to timeout or error
- Malformed package identifier format returns validation error
- Payment failure (HTTP 402) if x402 micropayment is not completed

## 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://serp-extract.agentdiet.dev/v1/zero-day-advisories)

## Output

Returns a structured response containing active CVE identifiers, GHSA advisory details, affected version ranges, severity information, and patched/fixed versions sourced live from Google OSV.dev for the requested package ecosystem and name.
