# 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 for live CVE and GHSA vulnerability advisories for PyPI, npm, Go, or Rust crate packages and returns patched version recommendations.

## 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-6b715711
```

Example prompt: Can you check OSV.dev for any active CVEs or GHSA security advisories affecting the PyPI package 'requests'?

## When to prefer this

Choose this endpoint when you need live, authoritative CVE and GHSA vulnerability data for open-source packages across PyPI, npm, Go modules, or Rust crates via OSV.dev. Prefer it over static databases or SCA tools when you need real-time advisory freshness and patched version guidance without maintaining a local vulnerability feed. Especially useful in agent workflows doing dependency auditing, CI/CD security gates, or supply chain risk assessment.

## Known failure modes

- Package identifier not found in OSV.dev — returns empty or error response
- Invalid ecosystem prefix causes query failure (e.g. unsupported ecosystem like Maven)
- OSV.dev upstream unavailable — service returns timeout or 5xx error
- Malformed package string (missing ecosystem separator) may return no results
- Package has no known vulnerabilities — returns empty advisories list (not an error)

## 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/maven-vuln-scanner)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory IDs, severity ratings, affected version ranges, patched/safe versions, and vulnerability descriptions sourced live from Google OSV.dev for the specified package ecosystem and name.
