# 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 PyPI, npm, Go, or Rust crate packages

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-d6d0bad4
```

Example prompt: Can you scan the npm package lodash for any known CVEs or GHSA security advisories and tell me which versions have patches available?

## When to prefer this

Choose this endpoint when you need real-time, authoritative vulnerability data sourced directly from Google OSV.dev for packages across PyPI, npm, Go modules, or Rust crates. It is ideal for automated CI/CD security gates, dependency audits, or supply-chain risk checks where freshness matters. Prefer it over static NVD scrapes or bundled SBOM tools when you need live CVE and GHSA advisory status including patched version information without maintaining a local vulnerability database.

## Known failure modes

- Package not found or unrecognized ecosystem returns empty vulnerability list or 404-style error
- Malformed package identifier (missing ecosystem prefix) may cause lookup failure or incorrect ecosystem resolution
- OSV.dev upstream unavailability causes delayed or failed responses
- Packages with no known vulnerabilities return an empty advisories array, which may be misread as an error
- Rate limiting or payment failure (HTTP 402) if call quota is exceeded

## 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/npm-vuln-scan)

## Output

Returns a structured object containing a list of active vulnerabilities for the queried package, including CVE IDs, GHSA advisory identifiers, affected version ranges, severity ratings, and the patched/fixed versions as sourced from Google OSV.dev in real time.
