# 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 llms-generator.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-23).

Queries Google OSV.dev to return active CVEs, GHSA advisories, and patched versions for a given 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 llms-generator-agentdiet-dev-real-time-open-source-package-cve-ghsa-43c7de43 -d '<json body>'
```

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, live CVE and GHSA vulnerability data from Google OSV.dev for open-source packages across PyPI, npm, Go modules, or Rust crates, especially in agent workflows that require up-to-date advisory intelligence without maintaining a local vulnerability database. Prefer it over static SBOM tools or cached vulnerability feeds when freshness matters.

## Known failure modes

- Package not found in OSV.dev — returns empty vulnerability list or 404-style response
- Invalid ecosystem prefix or malformed package identifier — returns validation error
- OSV.dev upstream API unavailable — service may timeout or return 503
- Package exists but has no known vulnerabilities — returns empty advisories array
- Payment not completed via x402 — returns HTTP 402 Payment Required

## 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://llms-generator.agentdiet.dev/v1/npm-vuln-scan)

## Output

Returns a structured object containing active CVE identifiers, GHSA advisory details (severity, description, aliases), affected version ranges, and recommended patched versions for the queried package from Google OSV.dev's live vulnerability database.
